Description
  • In this paper we present a new time-frequency transform called the Approximate Discrete Zolotarev Transform (ADZT), and demonstrate its efficacy in analysing non-stationary signals. Several experiments have confirmed two main properties of ADZT: i) in contrast to the Short-Time Fourier Transform (STFT) or the Wavelet Transform (WT), the choice of window type and length are not critical; and ii) the similarity between ADZT and the Fourier transform (FT) implies a simple physical interpretation of results in contrast to Wigner-Ville time-frequency distribution (WVD) or Choi-Williams time-frequency distribution (CWD).
