- * @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.
