Abstract
PURPOSE:To prevent the malfunction caused by the external noise by transmitting both the information signal and its complementary parity check signal with every bit. CONSTITUTION:When key 9 of keyboard 8 is switched on to generate, for example, 11001, 5-bit latch decoder 10 generates 11001. And this output is converted via 5-bit shift register 11 into the signals in terms of the sequential time. As the 1st, 2nd and 5th bits feature 1 each, two pulses featuring a short interval between pulses are generated from pulse generator circuit 13. While the pulses featuring a long interval between pulses are generated from pulse generator 14 since the 3rd and 4th bits feature 0 each. These pulses drive LED20 and 21 to be then transmitted in the form of the light. These transmitted signals are processed at the receiver and then judged 1 or 0 according to the length of the interval between pulses as to each bit. Furthermore, the length of the time is examined for the period from the 2nd pulse to each pulse of the next bit, and whether these pulses feature the complemental relation to the information contents of each bit is also confirmed.
