ABSTRACT:
An oversampling digital filter with Finite Impulse Response is implemented using a serial structure having a memory for the coefficients, a memory for the signal samples to be filter, a multiplier connected to the output of the memories, an accumulator connected to the output of the multiplier, and a simple control unit which controls these elements according to an input clock signal.
