1. A receiver comprising:
- an antenna receiving a radio wave transmitted from a communication target;
a demodulator extracting a baseband signal from said radio wave received by said antenna; and
a filter device low-pass filtering said baseband signal extracted by said demodulator, said filter device being configured to vary a cut-off frequency thereof in accordance with a command signal received from outside said receiver.

Abstract
The receiver includes an antenna for receiving a radio wave transmitted from a communication target, a demodulator extracting a baseband signal from the radio wave received by the antenna, and a filter device for low-pass filtering the baseband signal extracted by the demodulator. The filter device is configured to vary a cut-off frequency thereof in accordance with a command signal received from outside the receiver.

4. An electronic apparatus comprising:
-
a receiver including;
an antenna receiving a radio wave transmitted from a communication target;
a demodulator extracting a baseband signal from said radio wave received by said antenna; and
a filter device low-pass filtering said baseband signal extracted by said demodulator, said filter device being configured to vary a cut-off frequency thereof in accordance with a command signal received from outside said receiver;
and a control device outputting said command signal to said receiver in order that said receiver receives, on an alternating basis, different kinds of radio waves, which have the same frequency band, are modulated by the same modulation scheme, and are different in a baseband-signal frequency, for obtaining information contained in said different kinds of said radio waves. - View Dependent Claims (5, 6, 7)
