ABSTRACT:
The operating speed and dynamic input range of a digital FIR filter are markedly improved by encoding the signal by powers of two and using the thus encoded signal to shift (rather than multiply) the coefficient at each tap of the filter. A multiplexed shifter for simultaneously shifting all digits of the coefficient is also disclosed.
