| Abstract: | 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. |
