Abstract

PURPOSE:To realize data transmission system on a start-stop system of high efficient by correcting a step out by detecting the state of ''1'' when the data transmission becomes out of synchronism by transmission the (m)-number bit ''1''s equivalent to one word. CONSTITUTION:Start-stop system data are inputted to input terminal 10 and when the data are received in the order of a start bit, the data and a stop bit, data-reception end signal A becomes high in level. By fetching the data, control circuit 1 checks out whether or not the stop bit is received correctly. After a transmitting signal of (n) words which contains the start bit of the next word follows the start bit, ''1''s are transmitted more than (m) bits equivalent to one word and when the transmission becomes out of synchronism, the state of ''1'' is detected to correct the step out.
