Abstract
This paper presents a method of high-precision digital cymometer based on DSP. In the method, high-performance TMS320VC5402 DSP chip is used as the processing core, and the frequency of signals are calculated and corrected by an all phase FFT algorithm. At last, the frequency of the measured signal is displayed by the LED to real time. Experimental results show that the most relative errors of measurement are less than 0.5%, and the precision is high to meet the measurement needs.
