The Research of Intellectual Digital Frequency-measurement Meter Based on Virtual Instrument
This paper is about the design method of equal precision for frequency-measurement meter. The meter realizes the measurement calculating of frequency, period, PWM and duty cycle of the waveform. The measurement control of the whole measurement circuit is achieved by absolute interface of single chip, then the data is sent to PC in serial communication of single chip. The data procession and display is completed by LabVIEW.
