Decimation bit growth
WebR = decimation or interpolation ratio M = number of samples per stage (usually 1 but sometimes 2) N = number of stages in filter. Characteristics of CIC Filters Linear … 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 …

WebDec 29, 2024 · Looking at Decimation in Time algorithms, bit reversal is typically shown applied to the input. For Decimation in Frequency, it is typically shown applied to the output. My questions are: What happens if no bit reversal is performed? If the natural order is important, does it matter if the bit reversal is performed at the beginning or the end? WebThis question is of practical importance: when measuring a phenomenon, say at 1Hz, is it useful to use a very high sampling frequency such as 1kHz or more in order to improve …
