In the angle measurement, displacement measurement, it has a strong anti-interference ability and a stable and reliable output pulse signal. And after the pulse signal obtained by counting, the number of signals can be measured. Therefore, when we develope driving simulator for the steering wheel rotation angle measurement, we use EPC-755A optical encoder as the sensor. The outgoing circuit selects an open-collector. The output resolution selects 360 pulse / cycle. It needs the encoder output signal phase before counting. D flip-flop outputing Q (waveform W1) is high, Q (waveform W2) is low. It is sent to counter 74LS193 bi-directional, then thepulse is input plus CU to plus count; At this point, the following NAND gate is closed, the output is high (waveform W4).
