Arduino-based wow-and-flutter meter DSP frequency response

Summary

[edit]
Description
English: Arduino-based wow-and-flutter meter - desired frequency response for wide and narrow DSP IIR-filters. These exclude the effects of comb-like FIR filter caused by the sampling window (2.5 ms long in this case). Sampling further cuts the frequency response above 200 Hz.
Русский: Измеритель детонации (магнитофонов и ЭПУ) на основе ардуино. Частотная характеристика линейных БИХ-фильтров узкополосного и широкополосного каналов. Показанная АЧХ не включает влияние входного БИХ-фильтра окна выборки (время выборки 2.5 мс), который дополнительно срезает АЧХ выше 200 Гц.
