ABSTRACT:
A television tuner for use in a television receiver to receive a VHF band signal, a UHF band signal, and a satellite band signal converted from a received satellite signal, all of which are provided as a combined signal by a signal combiner. The television tuner includes an input terminal to receive the combined signal from the signal combiner, a first oscillator having a variable frequency, a first mixer to receive the combined signal and the output of the first oscillator to convert the combined signal into a first intermediate frequency signal if the VHF and UHF signals are to be utilized by the television receiver, or a second intermediate frequency signal if the satellite signal is to be utilized by the television receiver, first and second band-pass filters connected to the first mixer to receive first and second intermediate frequency signals, wherein the first band-pass filter is designed to pass the first intermediate frequency signal and the second band-pass filter is designed to pass the second intermediate frequency signal, and a processing circuit for processing the signals passed by the first and second band-pass filters to provide a standard VHF and UHF television signals and a frequency modulated satellite signal.
