| Abstract: | The system is a weak signal detection system based on MSP430G2553 microcontroller, the system can detect weak sine signals which are submerged in strong noise background and display the sine signal amplitude values.The whole system consists of power supply, adder, pure resistor divider network, band pass filter, A/D converter and the digital display circuit. Ultimately, the effective weak signal is detected in strong noisy environment. |
