A filter is an electrical network which is designed specifically to modify, in a prescribed way, an electrical signal applied to its input terminals. An elementary example would be a signal having only low-frequency and high-frequency components. A low-pass filter would permit only the low frequencies to be transmitted, the high frequencies being suppressed or attenuated. The converse is true for passing the high frequencies while suppressing the low frequencies by means of a high-pass filter.
