Abstract
The paper introduces the design of digital compoundfrequency meter based on DSP. The digital compound frequency meter can realize the mixing of the two input signal、the frequency and amplitude measurement、the rebuilding of input signal by using its AD unit、SCI unit、EV unit、PWM unit and peripheral circuit. The result of measurement will be displayed on PC. The thought of algorithm is that FFT algorithm is used to separate the mixed signal after repetitious sampling.The experimental results verify that the measurement error of amplitude is within 3. 5％ and the measurement error of frequency range is within 0. 1％, which meet requirements of the design.关键词
