摘    要:经典的等效采样方法,适用于采样频率等于或者略低于信号频率的场合,诸如雷达、微波测试设备等这些信号源受自身控制的高频测量设备.但是这些方法或者需要单独测量相位,或者需要固定的采样频率,操作复杂.如果信号是周期信号,且周期已知,为了获得这类信号的波形类型和幅值,提出一种新的等效采样方法,不但操作简单,而且采样频率可以远远低于信号频率.

关 键 词:Nyquist采样定理  等效采样  高频测量

Abstract:The classical equivalent sampling method,is suitable in the sampling frequency was equal to or is lower than the signaling frequency slightly the situation,specially to such as the radar,the microwave test facility and so on these supply oscillators own control high frequency measurement equipment is this.Perhaps but these methods need alone to survey the phase,or needs to fix the sampling frequency,the operation is complex.If the signal is the cyclical signal,also cycle known,in order to obtain this kind o...
Keywords:Nyquist sampling theorem  Equivalent sampling  High frequency measurement
