Abstract
A fixed latency configurable tap or fixed-tap digital filter may filter a signal in a fixed amount of time, regardless of the number of taps. The filter may include one or more of a clock, a plurality of registers in a shift register, an adder, an accumulator, and/or a scaler. In at least one embodiment, a running average may be maintained as samples are received such that the latency remains fixed with a constant number of clock cycles.
