A television receiver intended to decrease the number of expensive SAW filters to achieve low cost and a compact design. A trap circuit is interposed between a mixer and a SAW filter. During reception of a television signal, one of the trap frequencies at which the trap circuit responds is set to a video intermediate frequency on a television channel adjoining above an intermediate frequency band or a nearby frequency. The other trap frequency is set to a sound intermediate frequency on the adjoining television channel or a nearby frequency. During reception of an FM broadcast signal, the frequency of the FM broadcast signal is converted into a color subcarrier frequency on the intermediate frequency band or a nearby frequency. One of the trap frequencies is set to a substantially middle frequency between the video intermediate frequency and color subcarrier frequency on the intermediate frequency band.
