Each required bandpass filter is reduced to two lowpass filters which are relatively simple in design by using complexdemodulation. The decomposition and reconstruction architecture are introduecd.
利用复解调技术将设计带通滤波器组转化为设计相对简单的低通滤波器组问题，给出了分解与重构的系统流程。

With a minimum of mathematics and an engaging, highly rewarding style, Bloomfield provides in-depth discussions of harmonic regression, harmonic analysis, complexdemodulation, and spectrum analysis.
Time synchronization and carrier synchronization are cruxes of receiver. The reliability and stability of traditional analog demodulation are bad, and adjustment is complex.
