摘要
文章主要介绍一种水听器信号处理电路,主要包括前放电路、四阶带通滤波电路以及放大电路.该电路采用ADI公司的低噪声、低功耗的AD8605 和AD8608芯片,该电路的增益为 60 dB,滤波带宽为 200 Hz,等效电容输入噪声低.通过对水声信号进行放大和滤波,能够有效地从噪声信号中提取出目标信号.
Abstract
This paper mainly introduces a signal processing circuit of hydrophone,it mainly includes a front amplifier circuit,a fourth order bandpass filter circuit and an amplifier circuit.The circuit uses ADI,s low noise,low power AD8605 chip and AD8608 chip.The gain of the circuit is 60 dB,the operating bandwidth is 200 Hz,The equivalent capacitance input noise is low.By amplifying and filtering the underwater acoustic signal effectively,the target signal can be effectively proposed from the noise signal.
