This new method reduces the influence of time response of Fourier filtering on frequencymeasurementand improves the accuracy of transient frequency measurement.
Modulation domain analysis has become an important part for modern measurement technology. It is better than time domain andfrequency domain measurement when indicating frequency variable signal.
