Abstract:
1. A receiver, comprising: a filter which outputs an input signal containing a plurality of channels by rejecting an image band in a frequency converting process; a frequency converter having an analog orthogonal demodulator, which converts the frequency of said plurality of channels into a low range when the input signal whose image band has been rejected by said filter is inputted; an image rejecting device which rejects and outputs said image band of the signal of said plurality of channels whose frequency has been converted by said frequency converter; an A/D converter which converts the signal of said plurality of channels which is the output of said image rejecting device into a digital signal; and a channel selector which selects a desirable channel out of the signals of said plurality of channels contained in the output of said A/D converter by digital processing; wherein said frequency converter divides the input signals containing said plurality of channels into a plurality of sub-bands and converts the frequency of the output of said filter into the low range per each sub-band.
