S0876 NOISE REDUCTION SYSTEM ABSTRACT OF THE DISCLOSURE A method of and apparatus for reducing the noise of an input signal, such as a composite video signal. An orthogonal transform of the input signal is derived, this orthogonal transform having n transformed signal components. At least some of these signal components axe suppressed if their respective signal levels are less than a threshold level. Preferably, the n transformed signal components correspond to different portions of the input signal; and those components representing the higher frequency portions are suppressed if their signal levels are less than the threshold level. Following this signal suppression, the n transformed signal components are reconverted into substan- tially the input signal, less the suppressed components. -i-
