For a long-term working underwater sonar detection system, high-reliability low-power-consumption watch circuit is necessary. In this paper, a watch circuit system based on MSP430 is designed. Also, digital filtering using adaptive notch filter is proposed, and detection of wake-up signal with watch circuit is completed. The process of adaptive detective procedure, the simulation and the test results are particularly presented here.
