摘要	PURPOSE:To regenerate a reception pulse FM signal whose duty cycle is not 50% due to distortion so as to attain that the duty cycle is 50% by constituting the titled circuit with digital elements only such as a counter, a FIFO memory and a flip-flop. CONSTITUTION:An input signal having a reception waveform whose duty cycle is not 50% and having a period T is counted by a counter 102 for one period and 1/n=(n=1, 2...) of the output is written in the FIFO memory 103. The output of the FIFO memory is inputted to a counter 104, counted down by a clock having a period of n/2 times of the clock of the counter 102 and the state of a flip-flop 104 is changed at every generation of a borrow signal and then an output signal with 50% duty cycle is regenerated from the flip-flop.
