"WebSep 28, 2024 · The problem with using a frequency-selective filter on a signal with broadband noise is that the filter passes the noise in the signal within the filter’s passband as well as the signal. So eliminiating the broadband noise first makes the frequency-selective filtering (‘other filtering’ in my less than precise description) more effective. " - Elliptic filter matlab
