Band rejection is a phenomenon in waveform signals, where a certain frequency or range of frequencies are lost or removed from a source signal.
The term band rejection, when used in electronic signal processing, refers to the deliberate removal of a known frequency range - for instance, to compensate for a known source of interference (such as noise from mains (household) electricity). A specific frequency is removed using a notch filter.
In most other senses, band rejection is the unintentional loss of signal caused by imperfections in the recording, storage or reproduction of a waveform.
Famous quotes containing the words band and/or rejection:
“There was a young lady called Gloria
Who was had by Sir Gerald Du Maurier
And then by six men
And Sir Gerald again
And the band of the Waldorf-Astoria.”

“By Modernism I mean the positive rejection of the past and the blind belief in the process of change, in novelty for its own sake, in the idea that progress through time equates with cultural progress; in the cult of individuality, originality and self-expression.”
—Dan Cruickshank (b. 1949)
