微弱信號檢測裝置 四川理工學(xué)院 劉鵬飛、梁天德、曾學(xué)明 摘要: 本設(shè)計以TI的Launch Pad為核心板,采用鎖相放大技術(shù)設(shè)計并制作了一套微弱信號檢測裝置,用以檢測在強噪聲背景下已知頻率微弱正弦波信號的幅度值,并在液晶屏上數(shù)字顯示出所測信號相應(yīng)的幅度值。實驗結(jié)果顯示其抗干擾能力...
鎖定放大是微弱信號檢測的重要手段。基于相關(guān)檢測理論,利用開關(guān)電容的開關(guān)實現(xiàn)鎖定放大器中乘法器的功能,提出開關(guān)電容和積分器相結(jié)合以實現(xiàn)相關(guān)檢測的方法,并設(shè)計出一種鎖定放大器。該鎖定放大器將微弱信號轉(zhuǎn)化為與之相關(guān)的方波,通過后續(xù)電路得到正比于被測信號的直流電平,為后續(xù)采集處理提供方便。測量數(shù)據(jù)表明鎖定放...
