First of all, why do we need a transform, or what is a transform anyway? mathematical transformations are applied to signals to obtain a further information from that signal that is not readily available in the raw signal. in the following tutorial i will assume a time domain signal as a raw. Method to calculate the power spectral density using wavelet method. parameters. x : array like. the components of the field to apply wavelet tranform. dt: int. the sampling time of the timeseries. dj: determines how many scales are used to estimate wavelet coeff. (e.g., for dj=1 > 2**numb scales . mother wave: str. returns. The wavelet transform or wavelet analysis is probably the most recent solution to overcome the shortcomings of the fourier transform. in wavelet analysis the use of a fully scalable modulated window solves the signal cutting problem.

One of the goals of this tutorial is to illustrate how the wavelet decompo sition is carried out, starting from the fundamentals, and how the scaling functions and wavelets are generated from the filter theory perspective. The document introduces wavelet transforms as a relatively new concept that provides time frequency analysis of signals. it discusses the need for frequency analysis using transforms like the fourier transform and its limitations in analyzing non stationary signals. I see that you are trying to compute the power spectral density (psd) from the continuous wavelet transform (cwt) coefficients and compare it with the psd obtained from the fast fourier transform (fft).
