ABSTRACT:
An orthogonal demodulating section converts the frequency of received signals to the lower range after rejecting an image band thereof by an RE filter. An image rejecting section rejects the image band of the orthogonally converted output. It allows enough of an image rejecting degree to be obtained. An A/D converter section converts the whole range into a digital signal and an orthogonal demodulating section demodulates a desirable channel by means of digital processing. Then, a channel selecting section selects and outputs the desirable channel.
