WebDecimation is a method of observing only a periodic portion of the ADC samples, while ignoring the rest. The result is to reduce the sample … WebThe decimation part is just a valid toggle, can't think of any optimizations here. Oddly, it seems like the multiplication part is less resource hungry compared to all the additions at the output. A 14-tap filter doubled the resource usage (still no DSP), but increased the passband to … gurtband 50 mm
