Filed: 1987-12-24
Abstract: PURPOSE:To eliminate the effect of noise to be given onto a circuit operated at a video signal band and to obtain a frequency dividing circuit having a comparatively large frequency division with small-sized circuit constitution by combining outputs of plural ring counters having a frequency division ratio being in the relation of prime numbers to each other in a desired way, and decoding a signal. CONSTITUTION:An output of the n-stage of component of each ring counter is led in response to the residual (n-1) (n is an integral number being >=1) being the division of a value as the result of subtraction of '1' from a desired frequency division ratio of plural ring counters A-D whose frequency division ratios are selected to have the relation of prime numbers divided by the frequency division ratio of each ring counter and the outputs reaching a prescribed state simultaneously is detected by an AND gate 33 being a decoder. All the ring counters are reset in response to the decoded output of the decoding means and the frequency division output having a desired frequency division ratio is obtained in response to the reset output. Thus, the circuit scale is not increased, and the effect of noise to be given on other circuit is reduced.
