Filed: 1992-06-25
Abstract: PURPOSE:To determine a frequency highly precisely and to increase a response speed by shaping the waveform of a signal to be measured, by counting clocks for one period thereof and by determining the frequency on the basis of the number of the clocks. CONSTITUTION:The waveform of a signal of which frequency is to be measured is shaped in a wave-shaping circuit 2, only the waveform thereof in one period is put in a counter 10 through an input/output circuit 9 and the clocks in the period is counted. In order to determine the frequency on the basis of the count value thus obtained, interruption is made in CPU 6 at a rise of the object signal after the waveform of the signal is shaped and the value of the counter 10 is inputted. Then, the count value is inputted again by subsequent interruption and the difference thereof from the previously counted value is determined. The value of this difference is the period of the object signal and the frequency can be determined on the basis of this period. A clock of a prescribed frequency is put beforehand in the counter 10. Accordingly, analog circuits are lessened, execution of highly precise measurement is enabled by a digital processing and the response speed is increased by dispensing with an integrating circuit.
