Abstract
PURPOSE: To reduce the number of the component parts as well as to increase the response velocity by adding the adder and the edge trigger flip-flop to the arithmetictype low frequency measuring device which measures the cycle to obtain the frequency.
CONSTITUTION: When the input signal is supplied to terminal 1 for measurement of the frequency, one cycle of the input signal is detected by FF2. Output Q of FF2 and the clock signal applied to terminal 3 are applied to counter 5 to form the binary coded output. This output is applied to input A1W8 of adder 6 possessing input A1W8 of the augend, input B1W8 of the addend, sum output S1W8 and output terminal C0 of the carry signal each. At the same time, the output of output Q1W8 of edge trigger FF7 and the output of sum output S1W8 of adder 6 are applied to input B1W8 and data input D1W8 of FF7 respectively. The input signals are counted by counter 13 until the carry signal is applied from adder 6 to be displayed on display unit 14.
