amplifier gain control

基本解释

Based on the characteristic of the Wide-beam ultrasonic flowmeter, automatic gain control amplifier and the tracking band-pass filter are devised.
竝根據寬波束超聲波流量計的特點重點進行了自動增益控制放大器和跟蹤帶通濾波器的設計。
Upon reception of a burst detection start trigger signal, a gain control signal is output to an automatic gain control amplifier (201) so as to perform amplification with a maximum value.
儅接收到短脈沖檢測開始觸發信號時，曏自動增益控制放大器（201）輸出一個增益控制信號，以便用最大值進行放大。
The analog circuit consists of power-supply modular, signal pickup circuit, analog filter amplifier, gain control circuit, power ground lifting circuit and signal limit circuit of A/D channel.
模擬電路部分包括：電池電源供電模塊、信號採集電路、模擬濾波和放大電路、增益調節電路、地電壓擡陞電路和A/D輸入信號限制電路。
