Receiver

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 the low range in batch when the input signal whose image band has been rejected by said filter is inputted;
• an A/D converter which converts the signals of said plurality of channels whose frequency have been converted by said frequency converter into a digital signal;
• 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;
• and
• an image rejecting device which rejects said image band before, during or after said digital processing of said channel selector.

A receiver, comprising:

• filtering means for outputting an input signal containing a plurality of channels by rejecting an image band in a frequency converting process;
• frequency converting means having an analog orthogonal demodulator and converting the frequency of said plurality of channels into the low range in batch when the input signal whose image band has been rejected by said filtering means is inputted;
• image rejecting means for rejecting and outputting said image band of the signal of said plurality of channels whose frequency has been converted by said frequency converting means;
• A/D converting means for converting the signal of said plurality of channels which is the output of said image rejecting means into a digital signal;
• and
• channel selecting means for selecting a desirable channel out of the signals of said plurality of channels contained in the output said A/D converting means by digital processing.
