Abstract

PURPOSE: To make possible instant outputting of a pulse equal to two pulse number difference or frequency difference by providing a circuit which samples the second pulse with the first pulse and a circuit which erases the first pulse in accordance thereto.
CONSTITUTION: In a circuit 2, the pulses of input Ψ are sampled with input ϕ to detect the presence or not of pulses. If the two inputs are let to be ϕ, Ψ, output to be ω, and respective frequencies to be bϕ, bΨ, bω, then there is a relation of fϕ- fΨ=fω, and there is one pulse of Ψ or not at the maximum in 1 cycle of the inputϕ. When 1 pulse is detected in the circuit 2, the desired output pulse ω may be obtained by immediately erasing the pulse ϕ for 1 pulse in a circuit 3. Thereby, the digital logic circuit which instantly outputs the pulse having the frequency corresponding to the frequency difference of two input pulses or the pulse munber corresponding to pulse number difference may be obtained
