Optical Transfer Function - The Optical Transfer Function describes the spatial (angular) variation as a function of spatial (angular) frequency. When the image is projected onto a flat plane, such as photographic film or a solid state detector, spatial frequency is the preferred domain, but when the image is referred to the lens alone, angular frequency is preferred.

Continuous phase-frequency-shift keying - Continuous phase-frequency-shift keying (CPFSK) is a commonly-used variation of frequency-shift keying (FSK), which is itself a special case of analog frequency modulation. FSK is a method of modulating digital data onto a sinusoidal carrier wave, encoding the information present in the data to variations in the carrier's instantaneous frequency ...

Carrier frequency - Carrier frequency is a term used to designate the nominal frequency of a carrier wave, the center frequency of a frequency modulation signal, the frequency of the unmodulated electrical wave at the output of an amplitude modulated (AM), frequency modulated (FM), or phase modulated (PM) transmitter or the output of a transmitter ...

Center frequency - The center frequency f0 (resonant frequency) is the geometric mean between the lower cutoff frequency f1 and the upper cutoff frequency f2 of a frequency band. See also: Band-pass filter.
