Description

It is important to decompose complex action potential into constituent action potential trains.Several decomposition methods have been developed mainly using pattern matching technique. However,it is difficult to track the time-varying behavior of each action potential waveform. As an alternative to track time-varying decomposition,we compare recent time-varying spectrum techniques such as the short-time Fourier transform(STFT),the wavelet Transform(WT),and Karhunen- Loeve Transform(KLT).The signal of interest are needle myoelectric signals with firing table and simulate signals. As a result,we concluded that the WT is suitable for time- varying decomposition methods.
