ABSTRACT:
A comb filter has series connected integrators to which is fed a digital data stream at a high sampling rate in order to yield a digital data stream at a low sampling rate. The most significant bits of the digital data stream are reset in the first and second integrators, the resetting of the bits in the first integrator being stored in a counter. The counter reading of the counter is fed into the most significant bits of the last integrator at a reset time.
