Abstract

PURPOSE:To ensure the free variation for the pulse division ratio by controlling the operation of the pulse counter over a wide range by the control signal input and without giving the wiring ateration with every change of the operation. CONSTITUTION:Input bits I1-I9 of the input digital code are supplied to reading exclusive memory 9, and output bits O1-O4 of the digital code of the predetermined pattern are delivered. And the pulse used for the object of the counting is supsplied through the input pulse terminal in the form of one bit of the input digital code of memory 9. At the same time, prescribed output bits O5-O8 of the output digital code in memory 9 are supplied and memorized, and the D-type FF is provided to turn the memory of the output bits into input bits I6-I9 of memory 9. Then the reading of memory 9 is controlled by the control signal input to secure the free alteration for the pulse division ratio of counter output O1-O4.
