A jitter measuring method that helps the electronic system designer to reduce system jitter by tracing the jitter frequency variation and by detecting the transient jitter. The method includes below procedure: first, calculate the jitter of the signal to obtain signal jitter time trend waveform; then, decompose the jitter time trend waveform in the time-frequency domain to obtain the time varying frequency; after that, observe the decomposed results in time-frequency domain to trace out jitter frequency variation in time or to trace out transient jitter frequency and moment.
