Title:
TRANSMITTER-RECEIVER
Document Type and Number:
Japanese Patent JPH0637669
Kind Code:
A
Abstract:

PURPOSE: To eliminate the radio wave collision of both equipments at the time of simultaneous calling requirements by providing the transmission slot of a slave equipment by making it to coincide with the reception slot of a master equipment and providing the reception slot of the slave equipment by making it to coincide with the transmission slot of the master equipment at the time of an intermittent operation.

CONSTITUTION: An intermittent operation control means 19 outputs a timing pulse output (a) for transmitting and receiving a synchronization signal and a timing pulse signal output (b) for communicating information. In the case of the master equipment, a transmission signal generation means 17 is started by the output (a) to transmit the synchronization signal. On the other hand, in the case of the slave equipment, a reception signal generation means 16 is started by the output (a) to start the detection of the synchronization signal from the master equipment and to notify the synchronization signal to the means 19 at the time of detecting it. The means 19 finely adjusts an internal clock by making it to coincide with the detection of the synchronization signal. The timing pulse output (b) starts a transmission/ reception slot control means 18 to timing-control transmission and reception. The outputs c1 and c2 and the outputs d1 and d2 of the means 18 respectively control the reception operation of a reception means 14 and the transmission operation of a transmission means 15.
