Study of Enhancing Features of Digital Oscilloscope to Measure Period of Analog Modulation Signal

摘要：

This paper proposed enhancing a feature of digital oscilloscope(DSO)to measure period of modulation waveforill.It analyzed measurement robustness and solved availably the robustness of period measurement of modulation waveforill by selecting skiIIfully a reference Ievel and an iteralive algorithm.and proposed a method to avoid the difficulty of the estimation of the peaks number disturbed by sinail burrs wave on the top of peaks.At Iast it illuminated the application confine.This method is hoveI and simple which decreases greatly iterative steps and computational burden,and the error of period measurement is very small.Programming as a function and interpolating it into the function database of oscilloscopes,it is advantaged to realize feature of periodic measurement of modulation waveform in DSO.
