Title: Communication equipment
Inventor: AOKI HISASHI
IPC: B60R25/04
Filed: 1997-03-25
Abstract: PROBLEM TO BE SOLVED: To improve the communication performance by improving discrimination accuracy of pulse data. SOLUTION: When a resonance voltage exceeds a discrimination voltage, a transistor(TR) 29a of a resonance voltage detection circuit 29 is turned on and a low level high voltage detection signal is given to an input terminal Rx of a control circuit 23, and when the resonance voltage exceeds the discrimination voltage, the TR 29a is turned off and a high level low voltage detection signal is given to the input terminal Rx. When the input terminal Rx receives the high voltage detection signal, the control circuit 23 sets a reference time for pulse data discrimination to a 1st reference time 'P1±K%' and when the input terminal Rx receives the low voltage detection signal, the control circuit 23 sets a reference time for pulse data discrimination to a 2nd reference time 'P2±K%'.
