一种程控增益低噪声水声接收机的设计

Designing a Programmed-Gain-Control and Low-Noise Sonar Receiver

本文介绍了一种数字测深仪的接收机的具体设计 ,其特点是低噪声、增益程序控制 ,可以输出高质量的回波信号。稍加调整 ,即可用作其它声纳的接收机。

The design of an echo-sounder receiver is introduced in detail in this paper. Low noise and gain controlled by MCU program are the significant featuring of the receiver. The modularized filters make it suitable for different purpose.
