摘　　要：采用MSP430作为整个系统的主控制器,设计并制作了一套微弱信号检测装置,用于检测在强噪声背景下已知频率的微弱信号的幅度值,并在LCD上显示该值。最终测试表明,该系统能较好地实现微弱信号的检测,其抗干扰能力强,测量精度高。This design uses MSP430 as the main controller of the entire system and makes a weak signal detection device which is used to detect the amplitude values of the weak signal whose frequency is known in strong noise background , and the detection makes the amplitude value of detected signal display on the LCD digitally. The final tests show that the system can achieve the detection of weak signals with strong anti-interference ability and high measurement accuracy.
