Abstract :
By modelling a digital filter as a finite state machine, the minimum number of states can be used as a measure of the internal memory required. The memory efficiency of a first order digital filter subject to rounding or truncation is investigated. Specifically, we look at situations in which the input magnitude is normalised to unity, but the multiplier coefficient is allowed to vary
