資源簡介

（課程設(shè)計、參考資料）本文介紹兩種基于單片機的數(shù)字移相方法，借以說明實現(xiàn)移相的原理，并對兩種移相方法進行性能分析和比較。采用DDS技術(shù)生成兩路正弦波信號，并通過改變存儲器中數(shù)據(jù)讀取的起始地址來實現(xiàn)數(shù)字移相的功能。 原理：數(shù)字移相器方法——先將正弦波信號數(shù)字化，并形成一張數(shù)據(jù)表存入ROM芯片中，此后可通過兩片D/A轉(zhuǎn)換芯片，在單片機控制下連續(xù)地循環(huán)輸出該數(shù)據(jù)表，就可以獲得兩路正弦波信號。當(dāng)兩片D/A所獲得序列不同時，兩路信號便產(chǎn)生相位差。
