Abstract
A plural-conversion digital television signal receiver that embodies the invention upconverts digital television signal from a selected television channel to a UHF initial I-F signal. After image-rejection filtering there is a single-step downconversion of the initial UHF first I-F signal to a low-band final I-F signal, the uppermost frequency of which is in the high-frequency band. The low-band final I-F signal is digitized and demodulated in the digital regime to generate a baseband signal.
