There is provided a receiver equipped with a first and a second mixer circuits for performing the frequency conversion of a received signal into two intermediate-frequency signals, phases of which are orthogonal to each other, by means of two local oscillation signals, and a plurality of filter circuits for taking the intermediate-frequency signals out of the output signals of the first and the second mixer circuits. The receiver is further equipped with a demodulation circuit for taking a signal indicating broadcast contents of an analog broadcast or a digital broadcast out of the intermediate-frequency signals taken out by the filter circuits. The frequencies of the local oscillation signals are made to be a frequency apart from the carried frequency of the received signal by the intermediate frequency of the intermediate-frequency signals at a time of receiving the analog broadcast, and the frequency of the local oscillation signals are made to be a frequency equal to the center frequency of the received signal at a time of receiving the digital broadcast. <IMAGE> |
