components are attenuated or stopped. Bandpass filters are commonly used in radio transmitters and receivers to select a desired range of frequencies, in telephones to simultaneously eliminate DC and low frequency interference while limiting the signal bandwidth, and as elements of audio equalizers to either enhance or limit frequency bands for recording or playback.
