Abstract

PURPOSE:To enable the input control of the counter to the input signal of high frequency by controlling the input state of the delay circuit via the output of the delay circuit, thus eliminating the malfunction to the high frequency input. CONSTITUTION:Divider circuits 1-4 connected vertically are provided with the count input sent from terminal 61 used as the input, and the output of terminals 21, 23 and 24 among output terminals 21-24 plus input terminals 11-14 of circuits 1-4 are supplied to input terminal 17 of delay circuit 71 via NOR circuit 41. At the same time, circuits 1-4 are controlled by the output of set/reset switch circuit 51, and the count input is supplied to clock input terminal 47 of circuit 71. And circuit 71 is actuated by the initial count input. Then the output from output terminal 27 of circuit 71 is applied to circuit 51 and 41 to control the input state of circuit 71. As a result, the normal control is given to circuit 71 against the high frequency input signal, thus preventing occurrence of the malfunction.
