A multichannel video receiver having an analog-to-digital converter, fast-Fourier transform circuit and inverse-Fourier transform circuit. The analog-to-digital converter circuit generates a digitized representation of a frequency band used to convey a plurality of video signals, and the fast-Fourier transform circuit generates a frequency-domain representation of the digitized representation of the frequency band. The inverse-Fourier transform circuit recovers, from the frequency-domain representation, a plurality of digitized time-domain signals that correspond to the plurality of video signals. |
