amplifier gain control

基本解釋

Based on the characteristic of the Wide-beam ultrasonic flowmeter, automatic gain control amplifier and the tracking band-pass filter are devised.
并根據(jù)寬波束超聲波流量計的特點重點進(jìn)行了自動增益控制放大器和跟蹤帶通濾波器的設(shè)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.
當(dāng)接收到短脈沖檢測開始觸發(fā)信號時，向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(jìn)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.
