WebThe wavelet scales to use. One can use f = scale2frequency (wavelet, scale)/sampling_period to determine what physical frequency, f. Here, f is in hertz when the sampling_period is given in seconds. waveletWavelet object or name Wavelet to use sampling_periodfloat Sampling period for the frequencies output (optional). WebApr 1, 2012 · The wavelet transform (WT) is another mapping from L2 ( R) → L2 ( R2 ), but one with superior time-frequency localization as compared with the STFT. In this section, we define the continuous wavelet transform and develop an admissibility condition on the wavelet needed to ensure the invertibility of the transform.
