Abstract

PURPOSE:To compensate the delay of the signal rise time at the reception end for the start-stop type serial data transmission be carrying out the transmission by shortening the data of the side turning to a lower level on the transmission line less than the length of the normal 1-bit data. CONSTITUTION:Transmission signal 32 is blocked by gate 38 while transmission blocking FF37 is set. Transmission clock 33 is delivered 16times with every bit length of transmission data 32. In this circuit, transmission line 2-2 features a low level when data 32 is ''1''. The AND is secured for clock 33 via signal 32 and 34 and then supplied to the counter. The output of the counter is supplied to the decoder, and FF37 is reset by decoder output 36-10 corresponding to the first counter output. And the transmission signal is transmitted via gate 38, and FF37 is reset by output 36-10 to stop the transmission of the transmission signal. As a result,the length is shortened for the 1-bit data to compensate the signal rise at the reception side.
