What is the function of taps in a digital signal processing filter?
To reduce excess signal pressure levels
Provide access for debugging software
Select the point at which baseband signals are generated
Provide incremental signal delays for filter algorithms✓Correct answer
Explanation
A digital filter forms its output from a series of successively delayed samples. Each tap is one of those delay stages: its sample is multiplied by a coefficient and summed with the others to build the filter's response.
