Abstract :
A new method for the design of finite impulse response (FIR) filters whose discrete coefficient space is the power-of-two space is presented. We employ a vector successive approximation technique successfully used in data compression algorithms to produce a design method with a very low computational complexity that generates filters with implementation cost as low as those obtained by other, much more complex, optimization methods.
