DSP we eat for breakfast… that is the the moto of this board concept. Performing Wavelet decomposition every 20/16ms on 20k data points in less than 8/6.4 ms takes some serious optimization. Beside wavelet, board computes RMS and zero crossing point based on the ADC data captured from mains voltage at 1MSps arriving as PDM modulates signal using Machester line code.
