gain control amplifier

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。
The author bing have described the principle and proprty of the DK-1 auto-gain-control amplifier. Is the improvements for the auto-gain-control amplifier made before.
本文着重叙述了DK-1自动变挡放大器的原理和特点，这些特点就是对以前研制出的自动变挡放大器的改进。
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。
