WIRELESS RECEIVER

摘要

<P>PROBLEM TO BE SOLVED: To provide a wireless receiver for simultaneously receiving signals in a plurality of frequency bands with a simple structure. Ž<P>SOLUTION: The wireless receiver includes: an antenna part for receiving a high frequency radio signal; a reference signal generating means for generating first and second reference signals; first and second down converters for using the first and second reference signals to convert signals received by the antenna part into baseband signals; a first filter for selecting a prescribed frequency band from output of the first down converter; a first demodulation means for performing AM demodulation or FM demodulation to the signal selected by the first filter; a second filter for selecting from an output of the second down converter a prescribed frequency band; and a second demodulation means for performing AM demodulation or FM demodulation to the signal selected by the second filter.
