Method of Analyzing Signal Quality

摘要: A motion detecting system is disclosed where the signal from transducer analysed in a manner to distinguish between actual indicative of an intruder, typical noise expected for area under supervision and which indicates trouble condition (circuit failure, masking, or other having known signature). The samples provide simplified representation signal. results sampling process given sample period allows good assessment conditions supervised area. In preferred embodiment host experiment segments are compared within change therebetween with amount accumulated period. This measure particularly at different magnitude levels provides reliable basis assessing alarm conditions. approach can also be combined approaches recognizing only producing output based on analysis outputs various approaches.
