Abstract

PURPOSE:To control the width of a pulse to be discriminated by the clock signal, by connecting the storage output of the fundamental memory circuit to the input of the next stage and by comparing the logical value of each stage with the input signal and by transferring it to the next stage only when they coincide with each other. CONSTITUTION:Respective output terminals 12, 13, 14 and 15 of fundamental memory circuits 3, 4, 5 and 6 are initialized by the preset signal applied to terminal 7 and the preset polarity signal applied to terminal 8. By the signal input from sample clock terminal 2, the signal input from terminal 1 is sampled in circuit 3 as it is, and this signal is compared with the storage output signal of the fundamental memory circuit of the preceding stage respectively and is sampled only for coincidence in circuits 4, 5 and 6. By this method, the clock signal having period T shorter than time width T of logic change of the input signal is input to this device together with the input signal to obtain the output where logic change components of the input signal of (n+ or -1)XT time width or less are eliminated.
