Definatoin of low pass filter in fir digital

Answer 1

A low-pass filter is a filter that allows signals below a cutoff frequency (known as thepassband) and attenuates signals abovethe cutoff frequency (known as the stopband).By removing some frequencies, the filter creates a smoothing effect. That is, the filter produces slow changes in output values to make it easier to see trends and boost the overallsignal-to-noise ratiowith minimal signal degradation.
