/**
* @defgroup ConvolutionExample Convolution Example
*
* \par Description:
* \par
* Demonstrates the convolution theorem with the use of the Complex FFT, Complex-by-Complex
* Multiplication, and Support Functions.
*
* \par Algorithm:
* \par
* The convolution theorem states that convolution in the time domain corresponds to
* multiplication in the frequency domain. Therefore, the Fourier transform of the convoution of
* two signals is equal to the product of their individual Fourier transforms.
* The Fourier transform of a signal can be evaluated efficiently using the Fast Fourier Transform (FFT).
* \par
* Two input signals, <code>a[n]</code> and <code>b[n]</code>, with lengths \c n1 and \c n2 respectively,
* are zero padded so that their lengths become \c N, which is greater than or equal to <code>(n1+n2-1)</code>
* and is a power of 4 as FFT implementation is radix-4.
* The convolution of <code>a[n]</code> and <code>b[n]</code> is obtained by taking the FFT of the input
* signals, multiplying the Fourier transforms of the two signals, and taking the inverse FFT of
* the multiplied result.
* \par
* This is denoted by the following equations:
* <pre> A[k] = FFT(a[n],N)
* B[k] = FFT(b[n],N)
* conv(a[n], b[n]) = IFFT(A[k] * B[k], N)</pre>
* where <code>A[k]</code> and <code>B[k]</code> are the N-point FFTs of the signals <code>a[n]</code>
* and <code>b[n]</code> respectively.
* The length of the convolved signal is <code>(n1+n2-1)</code>.
*
* \par Block Diagram:
* \par
* \image html Convolution.gif
*
* \par Variables Description:
* \par
* \li \c testInputA_f32 points to the first input sequence
* \li \c srcALen length of the first input sequence
* \li \c testInputB_f32 points to the second input sequence
* \li \c srcBLen length of the second input sequence
* \li \c outLen length of convolution output sequence, <code>(srcALen + srcBLen - 1)</code>
* \li \c AxB points to the output array where the product of individual FFTs of inputs is stored.

/**
* @defgroup DotproductExample Dot Product Example
*
* \par Description:
* \par
* Demonstrates the use of the Multiply and Add functions to perform the dot product.
* The dot product of two vectors is obtained by multiplying corresponding elements
* and summing the products.
* \par Algorithm:
* \par
* The two input vectors \c A and \c B with length \c n, are multiplied element-by-element
* and then added to obtain dot product.
* \par
* This is denoted by the following equation:
* <pre> dotProduct = A[0] * B[0] + A[1] * B[1] + ... + A[n-1] * B[n-1]</pre>
*
* \par Block Diagram:
* \par
* \image html dotProduct.gif
*
* \par Variables Description:
* \par
* \li \c srcA_buf_f32 points to first input vector
* \li \c srcB_buf_f32 points to second input vector
* \li \c testOutput stores dot product of the two input vectors.

/**
* @defgroup FrequencyBin Frequency Bin Example
*
* \par Description
* \par
* Demonstrates the calculation of the maximum energy bin in the frequency
* domain of the input signal with the use of Complex FFT, Complex
* Magnitude, and Maximum functions.
*
* \par Algorithm:
* \par
* The input test signal contains a 10 kHz signal with uniformly distributed white noise.
* Calculating the FFT of the input signal will give us the maximum energy of the
* bin corresponding to the input frequency of 10 kHz.
*
* \par Block Diagram:
* \image html FFTBin.gif "Block Diagram"
* \par
* The figure below shows the time domain signal of 10 kHz signal with
* uniformly distributed white noise, and the next figure shows the input
* in the frequency domain. The bin with maximum energy corresponds to 10 kHz signal.
* \par
* \image html FFTBinInput.gif "Input signal in Time domain"
* \image html FFTBinOutput.gif "Input signal in Frequency domain"
*
* \par Variables Description:
* \par
* \li \c testInput_f32_10khz points to the input data
* \li \c testOutput points to the output data
* \li \c fftSize length of FFT
* \li \c ifftFlag flag for the selection of CFFT/CIFFT
* \li \c doBitReverse Flag for selection of normal order or bit reversed order
* \li \c refIndex reference index value at which maximum energy of bin ocuurs
* \li \c testIndex calculated index value at which maximum energy of bin ocuurs
*
* \par CMSIS DSP Software Library Functions Used:

/**
* @defgroup FIRLPF FIR Lowpass Filter Example
*
* \par Description:
* \par
* Removes high frequency signal components from the input using an FIR lowpass filter.
* The example demonstrates how to configure an FIR filter and then pass data through
* it in a block-by-block fashion.
* \image html FIRLPF_signalflow.gif
*
* \par Algorithm:
* \par
* The input signal is a sum of two sine waves: 1 kHz and 15 kHz.
* This is processed by an FIR lowpass filter with cutoff frequency 6 kHz.
* The lowpass filter eliminates the 15 kHz signal leaving only the 1 kHz sine wave at the output.
* \par
* The lowpass filter was designed using MATLAB with a sample rate of 48 kHz and
* a length of 29 points.
* The MATLAB code to generate the filter coefficients is shown below:
* <pre>
* h = fir1(28, 6/24);
* </pre>
* The first argument is the "order" of the filter and is always one less than the desired length.
* The second argument is the normalized cutoff frequency. This is in the range 0 (DC) to 1.0 (Nyquist).
* A 6 kHz cutoff with a Nyquist frequency of 24 kHz lies at a normalized frequency of 6/24 = 0.25.
* The CMSIS FIR filter function requires the coefficients to be in time reversed order.
* <pre>
* fliplr(h)
* </pre>
* The resulting filter coefficients and are shown below.
* Note that the filter is symmetric (a property of linear phase FIR filters)
* and the point of symmetry is sample 14. Thus the filter will have a delay of
* 14 samples for all frequencies.
* \par
* \image html FIRLPF_coeffs.gif
* \par
* The frequency response of the filter is shown next.
* The passband gain of the filter is 1.0 and it reaches 0.5 at the cutoff frequency 6 kHz.
* \par
* \image html FIRLPF_response.gif
* \par
* The input signal is shown below.
* The left hand side shows the signal in the time domain while the right hand side is a frequency domain representation.
* The two sine wave components can be clearly seen.
* \par
* \image html FIRLPF_input.gif
* \par
* The output of the filter is shown below. The 15 kHz component has been eliminated.
* \par
* \image html FIRLPF_output.gif

* @defgroup GEQ5Band Graphic Audio Equalizer Example
*
* \par Description:
* \par
* This example demonstrates how a 5-band graphic equalizer can be constructed
* using the Biquad cascade functions.
* A graphic equalizer is used in audio applications to vary the tonal quality
* of the audio.
*
* \par Block Diagram:
* \par
* The design is based on a cascade of 5 filter sections.
* \image html GEQ_signalflow.gif
* Each filter section is 4th order and consists of a cascade of two Biquads.
* Each filter has a nominal gain of 0 dB (1.0 in linear units) and
* boosts or cuts signals within a specific frequency range.
* The edge frequencies between the 5 bands are 100, 500, 2000, and 6000 Hz.
* Each band has an adjustable boost or cut in the range of +/- 9 dB.
* For example, the band that extends from 500 to 2000 Hz has the response shown below:
* \par
* \image html GEQ_bandresponse.gif
* \par
* With 1 dB steps, each filter has a total of 19 different settings.
* The filter coefficients for all possible 19 settings were precomputed
* in MATLAB and stored in a table. With 5 different tables, there are
* a total of 5 x 19 = 95 different 4th order filters.
* All 95 responses are shown below:
* \par
* \image html GEQ_allbandresponse.gif
* \par
* Each 4th order filter has 10 coefficents for a grand total of 950 different filter
* coefficients that must be tabulated. The input and output data is in Q31 format.
* For better noise performance, the two low frequency bands are implemented using the high
* precision 32x64-bit Biquad filters. The remaining 3 high frequency bands use standard
* 32x32-bit Biquad filters. The input signal used in the example is a logarithmic chirp.
* \par
* \image html GEQ_inputchirp.gif
* \par
* The array <code>bandGains</code> specifies the gain in dB to apply in each band.
* For example, if <code>bandGains={0, -3, 6, 4, -6};</code> then the output signal will be:
* \par
* \image html GEQ_outputchirp.gif
* \par
* \note The output chirp signal follows the gain or boost of each band.
* \par

* \li \c testRefOutput_f32 points to the reference output data

* <b> CMSIS DSP Software Library -- Linear Interpolate Example </b>
*
* <b> Description </b>
* This example demonstrates usage of linear interpolate modules and fast math modules.
* Method 1 uses fast math sine function to calculate sine values using cubic interpolation and method 2 uses
* linear interpolation function and results are compared to reference output.
* Example shows linear interpolation function can be used to get higher precision compared to fast math sin calculation.

*
* \par Description:
* \par
* Demonstrates the use of Matrix Transpose, Matrix Muliplication, and Matrix Inverse
* functions to apply least squares fitting to input data. Least squares fitting is
* the procedure for finding the best-fitting curve that minimizes the sum of the
* squares of the offsets (least square error) from a given set of data.
*
* \par Algorithm:
* \par
* The linear combination of parameters considered is as follows:
* \par
* <code>A * X = B</code>, where \c X is the unknown value and can be estimated
* from \c A & \c B.
* \par
* The least squares estimate \c X is given by the following equation:
* \par
* <code>X = Inverse(A<sup>T</sup> * A) * A<sup>T</sup> * B</code>
*
* \par Block Diagram:
* \par
* \image html matrixExample.gif
*
* \par Variables Description:
* \par
* \li \c A_f32 input matrix in the linear combination equation
* \li \c B_f32 output matrix in the linear combination equation
* \li \c X_f32 unknown matrix estimated using \c A_f32 & \c B_f32 matrices
