Constant-Q, Data-Adaptive, and Quadratic Time-Frequency Transforms
Obtain the constant-Q transform (CQT) of a signal, and invert the transform for perfect reconstruction. Decompose a signal using an adaptive wavelet subdivision scheme. Perform data-adaptive time-frequency analysis of nonlinear and nonstationary processes. Decompose a nonlinear or nonstationary process into its intrinsic modes of oscillation. Obtain instantaneous frequency estimates of a multicomponent nonlinear or nonstationary signal. Return the Wigner-Ville and cross Wigner-Ville distributions of signals.
