Abstract

In engineering and experiment, it is often necessary to measure the frequency, period, duty cycle and other information of signal accurately. There are many kinds of measurement methods. In literature, the equal precision measurement method is proposed. Based on CPLD and MSP430 single chip microcomputer, the measurement of high frequency signal frequency is realized. In reference, a special chip tdc-gpx2 is used to measure the frequency of high frequency signal. In reference, the frequency measurement method of frequency shift filter is proposed, which realizes the measurement of frequency in power system and effectively removes interference.
