IPC: G05B19/05
Filed: 1991-12-11
Abstract: PURPOSE:To make the circuit small and to improve the safety and the responsiveness by eliminating a short time OFF signal from an output signal resulting from an input signal rectified and sent through isolation, obtaining a digital output signal, and thereby eliminating the need for a smoothing capacitor. CONSTITUTION:A diode bridge rectifier circuit 3 rectifies an AC power voltage Vin in terms of full wave and outputs a unipolar rectified voltage Vrec. A signal isolation means PC is driven by the voltage Vrec and an isolation digital signal DB including a short pulse signal is outputted at an output terminal of a buffer BUF. A digital filter circuit 4 eliminates a short time OFF signal (short pulse signal) in the signal DB to be sent through the means PC and outputs a digital output signal DI. The signal DI has some delay in its leading and trailing respectively and nearly 40% at a maximum period of an AC power supply I and the value does not almost give any effect in the usual operation. Thus, a smoothing capacitor is not required and the circuit is made small and the safety and the responsiveness are improved.

IPC: H04L27/34
Filed: 1990-11-28
Abstract: PURPOSE:To simplify circuit configuration on the reception side by transmitting the combination of signal points different from the combination of signal points on plural phase planes applied to an information symbol as a synchronizing signal, discriminating the combination of the signal points on the reception side and establishing frame synchronization and the synchronization of the combination of the signal points. CONSTITUTION:A ROM 2 outputs bit trains D11 and D12 so that the bit patterns of inputted nine information bits can be correspondent to the combination of each one signal point on the first and second phase planes. A parallel/serial conversion circuit 3 executes parallel/serial conversion from the bit trains D11 and D12 to six bit trains, inputs them to a modulator 4 and generates a modulated signal M. On a reception side 20, a demodulator 5 demodulates the received modulated signal M and outputs the six bit trains to a coincidence judgement circuit 6 and a serial/parallel conversion circuit 7. The coincidence judgement circuit 6 compares the bit patterns of the continuous two time slots of the inputted bit trains with the bit pattern expressing the combination of signal points corresponding to the frame synchronizing symbol and outputs a frame pulse F2 synchronously with the timing of the first time slot among the coincident and continuous two time slots.
