Title: Data transmission equipment
Inventor: YAMAKAWA KUNIO
IPC: H04L27/10
Filed: 1986-02-13
Abstract: PURPOSE:To decrease data transmission error by setting bits of parallel input of a shift register at the transmitter side as required in an asynchronous data transmitter using FSK modulation. CONSTITUTION:The 1st bit 8 of the parallel input of the shift register 3 is set to '1' at the sending side and the 2nd bit 9 is set to '0' and transmission data are inputted to the 3rd succeeding bits. After the carrier is detected at the reception side, and after a time 1/2D (D is data transmission speed) when an FSK demodulation output after a certain time changes from '1' to '0', the FSK demodulation output is read. Then it is confirmed that the first FSK demodulation output is '0' and then the reception data is obtained from the FSK demodulation output read at every time 1/D. Thus, data transmission error is reduced independently of the variation of the circuit and the strength of the reception signal.
