The square wave source is an impulse source in which digital technique is used. It has the advantages of rigid phase, high frequency stabilization and high antijamming.
方波电源是采用数字技术的脉冲电源，具有相位严格、频率稳定度高，抗干扰能力强等独特的优点。

The resulting controller is a finite impulse response (FIR) filter and hence problem of non-minimum phase zero cancellation is avoided.
这种控制器给出了避免非最小相位过程零极点对消的有限脉冲响应滤波器。

The orthogonal analog phase lock loop is used to get the timing information of the impulse radio system and the multi-path component separation.
