n.前級擴大機;前置增幅器
It still is offerred dog the options such as generator and preamplifier. 它還供給跟蹤發(fā)生器和前置放大器等選件。
The PA7:4 preamplifier is available for J16Quad and J10Quad detectors. 該pa7:4前置供j16quad和j10quad探測器。
The receiver has been designed and made, including preamplifier,amplifier, filter circuit, AGC, PLL, etc. 設計并制作了接收機電路,包括前放電路,放大電路,濾波電路,自動增益控制電路,鎖相環(huán)電路,判決電路等。
This paper presents an up-to-date design of bioelectric preamplifier with low noise- high common-mode-rejection ratio (CMRR) and high impedance. 本文介紹一種利用負反饋原理由集成運算放大器構成的低噪聲、高共模抑制比、高輸入阻撫前置放大器。
The key to the design of feeble signal sampling system lies in the designing of ultra low noise preamplifier. 設計超低噪聲前置放大器是設計微弱信號采集儀器時不可回避的技術問題。
Main amplifier is used for amplifying the output signal of preamplifier into digital voltage level. 主放大器把前置放大器的輸出信號放大到數字邏輯電平,并且保持數字電平的恒定,以實現(xiàn)限幅的功能。
