Abstract:
    The invention relates to a digital signal processing method. The method solves the problem of unable to obtain the accurate wideband harmonic phase by using the existed technique. Based on the NTN correct technique, this invention obtains a serious wideband impulses, corrects orderly their time base aberration, uses average signal shift to eliminate co-modulate interference, corrects mismatch aberration, and signal dithering. Then phase-spreading and eliminating linearization against the obtained phase frequency response function obtains the harmonic phase. Finally, the phase uncertainty can be obtained by means of introducing the error spread formulation and assumption verification estimation in the complex frequency area. The wideband phase obtained by this invention can be used in the phase correction in large-signal network analyzer and hi-speed sampling oscilloscope.
