Electronic filters are electronic circuits which perform signal processing functions, specifically to remove unwanted frequency components from the signal, to enhance wanted ones, or both. Electronic filters can be:
passive or active
analog or digital
high-pass, low-pass, bandpass, band-reject (band reject; notch), or all-pass.
discrete-time (sampled) or continuous-time
