What is the function of taps in a digital signal processing filter?
Pick an answer to check it.
Answer: D. Provide incremental signal delays for filter algorithms
Taps are the points along a DSP filter's delay line where delayed copies of the signal are taken and weighted. They provide the incremental delays the filter algorithm combines.
Tip: Taps = delay steps in the filter.
