ABSTRACT:
An HDTV receiver is disclosed including a tuning portion for selecting one of a plurality of RF signals received, and converting a selected RF signal into an intermediate frequency signal; a demodulator/FPLL for demodulating the intermediate frequency signal output from the tuning portion into a baseband signal in which the frequency and phase are locked, and outputting an AFC signal; a first local oscillator for forming a frequency signal which can be varied from a reference frequency to a specific frequency, and outputting the thus-formed frequency signal to the demodulator/FPLL; and a VSB filter for VSB-filtering the baseband signal output from the demodulator/FPLL.
