Normalized Frequency (digital Signal Processing)
In digital signal processing, the normalized frequency of a periodic signal is its frequency expressed in units of cycles (or radians) per sample, rather than in the usual SI units of hertz (cycles per second). The cycles-per-sample frequency is computed by dividing the cycles-per-second frequency by the sampling rate (samples per second); symbolically, the "per second" units cancel:
- (cycles/second) / (samples/second) = cycles/sample.

Famous quotes containing the words frequency and/or signal:
“One is apt to be discouraged by the frequency with which Mr. Hardy has persuaded himself that a macabre subject is a poem in itself; that, if there be enough of death and the tomb in one’s theme, it needs no translation into art, the bold statement of it being sufficient.”
—Rebecca West (1892–1983)
“Perhaps having built a barricade when you’re sixteen provides you with a sort of safety rail. If you’ve once taken part in building one, even inadvertently, doesn’t its usually latent image reappear like a warning signal whenever you’re tempted to join the police, or support any manifestation of Law and Order?”
—Jean Genet (1910–1986)
