Abstract
PURPOSE:To ensure an easy and accurate detecion of synchronism at the side of question, by generating the clock based on the question signal and then producing the answer signal in the timing of the clock. CONSTITUTION:The clock generating circuit 8 is provided to generate the clock necessary for actuation of the logic circuit by using directly the cycle of the question signal A received 1 or several cycles in collection for the period equivalent to one bit. The sequence circuit 9 receives the clock signal from the circuit 8 and then extracts the proper information stored in the ROM3 in the form of the binary information and in the form of the serial binary signal to then apply it to the gate circuit 10. Then the circuit 10 transmits or blocks the signal current of the signal A, and thus delivers the answer signal B possessing the two different types of states which can identify the signal current of the signal A as it is or the current value 0 and based on the proper information to send the signal B to the side of question via the transmission circuit 7. In such constitution, the synchronism is detected at the side of question in an easy and accurate way.
