Detailed Documentation

In signal time domain analysis, we can employ multiple methods including but not limited to continuous wavelet analysis, Wigner-Ville distribution, and short-time Fourier transform. These techniques enable comprehensive understanding of signal characteristics and properties, providing valuable insights and information. MATLAB implementations typically involve specialized functions like cwt() for continuous wavelet transforms, spectrogram() for short-time Fourier analysis, and wvd() for Wigner-Ville distribution, each requiring proper parameter configuration for optimal time-frequency resolution trade-offs. The continuous wavelet transform excels in multi-resolution analysis through scalable mother wavelets, while Wigner-Ville distribution offers high resolution but may suffer from cross-term interference in multi-component signals. Short-time Fourier transform provides a balanced approach using sliding window techniques to capture local frequency content over time.
