Abstract：Toadapttothe competency-oriented training needs ofmaster'sstudents majoring inelectronic informationunder the backgroundof new enginering，this studybuilds ateaching case database around thecourseof modern signal processing technology.Itadoptstheconceptsofmodulardesign，task-drivenandinterdisciplinaryintegrationandcovers theapcatiosof core modernsignal processingtechnologies suchas wavelet analysis，Bayesian estimation，Kalman filtering and Wienerflring intypical scenarios including medicine，radarand communication.Itfocuses on developing twocases：avideo mult-target tracking case that itegrates YLOv5 withKalman fltering andanECGclassificationcase based on wavelet threshold denoising andSVM，andteseasscoverpacticaloerationprocessesicdingsignalacqusitionlgorithiplemetationdte evaluation.Throughtheintegrateddesignof teachingobjectives-caseresources-technicaltools-evaluationmechanisms，the studyeffectivelyimprovesstudents’abilitiesinmodelinganalysis，lgorithmimplementationandengineeringapplicationand provides a promotable practical paradigm for curriculum optimization and competency development.
