Abstract

PURPOSE: To make signal conversion possible through accurate self-synchronization with input pulses even if an input signal shifts in pulse position, by making a decision on a pulse code by the number of clock signals in a space period of an input pulse position demodulated signal.
CONSTITUTION: A pulse-position modulated signal expressed by spaces, differing in time width by pulses of constant time width and codes is applied to input terminal 3. From clock input signal terminal 12, a clock signal with a frequency much higher than the fundamental frequency of the input signal is applied. Then, FF20 and inverter 18-2, for example, opens gate 16-3 only in the space period of the input signal to pass clock pulses through and pulses are divided and counted by counter 19. In addition, a pulse code is judged by this count value and, for example, when it is three or four, counter 19 generates an output. By this output signal, the output of a control counter is outputted from an outoput block respectively.
