Continuous transition and synchronous detection from am signal to dsb signal 信號的連續(xù)過渡與同步檢波
4 . in data acquisition system , the application of phase - locked and synchronous detection reduce the cost of the whole system and improve the sensitivity . carrier signal and modulation signal achieve entirely synchronous too 數(shù)據(jù)采集系統(tǒng)采用鎖相技術(shù)、同步檢波的原理,降低了整個系統(tǒng)的成本,提高了靈敏度,并使得載波信號與調(diào)制信號完全達(dá)到同步。
