Claims

[Scope of claims for utility model registration] (1) Input pulses with period T and duty ratio 1/2 are
A counter that is cleared every time 2N+1 is counted as a natural number, and a duty ratio of N2N+1 with the period (2N+1)T output from this counter.
A delay circuit that delays the pulse by 1/2T, an output pulse of this delay circuit, and the above duty ratio N2
Equipped with an OR gate that inputs N+1 pulses,
A 2N+1 frequency divider circuit that extracts the OR gate output as a frequency divided output pulse. (2) The 2N+1 frequency divider circuit according to claim 1, wherein said delay circuit is constituted by a D flip-flop or a D type transparent latch circuit using said input pulse as a clock.
