WebAug 28, 2016 · within the filter can experience overflow. (An integrator’s gain is infinite at DC!) As such, the use of two’s complement (non-saturating) arithmetic resolves this overflow situation just so long as the integrator word width accommodates the maximum value expected at the CIC filter output. WebJul 29, 2024 · 3 - Assuming there can be no overflow at the output of the filters, now you need to determine how many "fractional bits" you need to keep. There are no simple answers. Assuming no decimation, it could be a good idea to keep the output format the same as the input. For example, 14-bit input with 1 sign-bit ---> 14-bit ouput with 1 sign bit.
