Method and device for receiving at least one input signal containing at least one piece of coded information.

摘要

The method involves feeding input radio signals to an antenna (11) and a preamplifier (13). The signals are passed to a phase splitter (14) which separates the signals into two parts in phase opposition. One of the outputs is passed through a quartz resonator (18) and resistor (19) while the other output is passed through a compensation circuit, a resistor (22) and capacitor (11) connected in series. The outputs of the two paths are combined and amplified by a variable gain amplifier (25), reducing out of band signals. Signals are passed to an amplitude demodulator (26) and adaptive comparator (27) which outputs coded information (33).
