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.
并根据宽波束超声波流量计的特点重点进行了自动增益控制放大器和跟踪带通滤波器的设计。
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.
当接收到短脉冲检测开始触发信号时，向自动增益控制放大器（201）输出一个增益控制信号，以便用最大值进行放大。
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.
模拟电路部分包括：电池电源供电模块、信号采集电路、模拟滤波和放大电路、增益调节电路、地电压抬升电路和A/D输入信号限制电路。
