The architecture is a very economical implementation because digital multipliers are not required. It is imple-
mented by cascading 4 integrators operating at full sampling rate (XTI/2) followed by 4 differentiators operating
at the reduced sampling rate (XTI/2/16). Also wrap around logic is allowed and the internal overflow will not af-
fect the output signal as long as a minimum required bit width is maintained.
The transfer function of this Sinc4/16 filter is:
with K = 4, M = 16
and its frequency response is:
with
Figure 4. Transfer function of a 4th order Sinc Filter, decimation factor is 16.
