Abstract

PURPOSE:To obtain economical and simple pulse generators by using a pulse generator for a time division multiplex transmitting device by means of PWN in common with respective offices. CONSTITUTION:Clock pulse generator 5 generates pulses by means of the switching operation of transistor Tr2 and sends the pulses to line 3 connected in the form of party lines to transmitter/receiver 6 of each office. In case of transmition of data, photocoupler Pc1 of a transmitting office receives the clock pulses, the inner timing is regenerated by use of the decay operation and photocoupler Pc2 and Tr3 are switched according to the transmitted data, so that the clock pulses are modulated and a PWM pulse array is sent to line 3. In the receiving office, the data used when the PWM pulse array is received by photocoupler Pc1 are demodulated. therefore, common pulse generator can be used and it is unnecessary to use an individual pulse generator in each office and to cooperate plural pulse generators, so that economical pulse generators can be obtained.
