Abstract
A finite impulse response (FIR) filter includes a coefficient generator that generates M coefficients, where M is an integer greater than one, M storage elements each storing one of the M coefficients, and a bus. A selector circuit selectively connects the coefficient generator to the M storage elements one at a time via the bus to update the coefficients of the M storage elements.
