Spectrogram analysis of selected tremor signals using short-time Fourier transform and continuous wavelet transform
spectrogram wavelet transform broadband tremor
2015/10/8
Among a variety of spectrogram methods Short-Time Fourier Transform (STFT) and Continuous Wavelet Transform (CWT) were selected to analyse transients in non-stationary tremor signals. Depending on the...
