Question

Why is digital filtering involved in digital signal processing?

Answer 1

Answer:

In signal processing, a digital filter is a system that performs mathematical operations on a sampled, discrete-time signal to reduce or enhance certain aspects of that signal. ... Digital filters can often be made very high order, and are often finite impulse response filters which allows for linear phase response
