The phase - locked amplifier is realized through labview 此相關(guān)器用labview語言實現(xiàn)。
Sampling frequency and time constant of phase - locked amplifier were increased by using microcomputer 采用計算機(jī)采樣,提高了采樣頻率和鎖相放大器的時間常數(shù)。
Last , because the slight optical signal of optical ct usually immerses in the noise signals , a phase - locked amplifier using correlation function is proposed in this paper . the phase - locked amplifier can acquire the slight optical signal immersing in the noise signals 此外,由于光學(xué)ct微弱的光信號往往會被外來的干擾光淹沒,所以本文還研究了一種基于相關(guān)函數(shù)的相關(guān)器,用來提取淹沒于噪聲中的被調(diào)制的微弱光信號。
