Title:
METHOD AND CIRCUIT FOR SETTING SLICE LEVEL
Document Type and Number:
Japanese Patent JPH05327799
Kind Code:
A
Abstract:
PURPOSE: To stably and surely slice a demodulated output, even if a demodulation characteristic of a demodulating circuit is dispersed or fluctuated.
CONSTITUTION: A circuit 17 for forming a prescribed pulse P17 during a period of time when a communication is not being executed is provided. A transmitting circuit 20 for feeding a non-modulating signal S20 to a receiving circuit 10 by the pulse P17 is provided. A circuit 14 for holding a level of a signal P11 obtained by allowing the non-modulating signal S20 to undergo FM demodulation is provided. A circuit 12 for slicing a signal S11 demodulated in FM from a receiving signal, based on this held level as a reference is provided.
