摘要
微弱信号检测就是利用近代电子学和信号处理方法从噪声中提取有用信号,其关键在于抑制噪声,恢复、增加和提取有用信号。本设计基于单片机MCF51QE128,通过处理高速模/数转换芯片AD7760采集的信号,利用硬件过滤电路以及软件的处理,完成微弱信号的检测及提取方面的研究。
Weak signal detection is to extract the useful signal from the noise using modern electronics and signal processing method, and the key is to suppress noise, recovery, increase and extract useful signal. The design is based on microcontroller MCF51QE128. By pro eessing the signal, the signal is acquired through high-speed analog-digital conversion chip AD7760. This design uses hardware filter cir-cuitry and software processing, and completed the study of detecting and extracting the weak signal.
