Abstract
PURPOSE:To secure the synchronous data transmission in a simple way via a single circuit by forming the synchronous signal part with the asymmetric clock signal. CONSTITUTION:Synchronous signal ST is supplied to NAND gate 1 along with clock signal CP to obtain output (a). Signal (a) is piled on the data signal to obtain signal (b). Signal (b) is transmitted via single circuit l. At the reception side noise (n) mixed in from input signal (c) is eliminated, and output (d) is supplied to data signal detection circuit 8 and synchronous signal detection circuit 7. Circuit 8 compensates the break part of signal (d) via the one-shot multi which is a little longer than time duration (t). Circuit 7 possesses the one-shot multi featuring time duration T and compensates the break part of signal (e) supplied via one-shot multi-vibrator 6 of time duration 1.5T to obtain synchronous signal RT.
