Its synchronous phase-shift function is produced by microcomputer auto-matically, the VFC and counter-gate act as a PSD, and fhe counter combin-ing with real time processing of smoothing act as the LPF.

- 其同步移相控制由微處理器自動(dòng)產(chǎn)生,相敏檢波(PSD)的功能由V/F轉換結構(VFC和計數門(mén))來(lái)執行,低通濾波(LPF)的作用由計數器與實(shí)時(shí)平滑處理來(lái)實(shí)現。 從而可恢復掩沒(méi)在非相干噪聲中的單次信號,并取得肯定的S/N改善。
