Abstract
A novel Finite Impulse Response filter (FIR) Filter is provided which includes a plurality of multipliers (14-22), a plurality of multiplexers (24-32), and a plurality of sample and hold circuits (34-42). At least two of the sample and hold circuit output signals (1-5) may be multiplexed in a round robin fashion to at least two of the multipliers (14-22). The multipliers may receive as a second input, fixed tap coefficient signals (C.sub.1 -C.sub.5) for multiplication with the multiplexed sample and hold circuit output signals (1-5).
