Claims

[Scope of utility model registration request]

A parametron frequency divider that generates a half frequency that is synchronous with the number of input cylinders, a waveform shaping circuit that converts the output signal waveform of this frequency divider into a square wave, and a waveform shaping circuit that operates alternately with the square wave input. The switching circuit operates synchronously with the input frequency to output a frequency that is half the input frequency, and when the input phase is inverted, the output phase changes. is from the phase before inversion■9
A frequency divider characterized by changing by 0° or 090°.
