WebApr 7, 2024 · 1.1 Fourier transform. In our mind a (1D) signal is nothing but a time series. This means that we have an x axis, which is the time, and a y axis, which is the quantity we are considering (e.g. voltage). From an intuitive point of view, doing a Fourier transform of a signal means to see this signal in another domain. WebPyWavelets is open source wavelet transform software for Python. It combines a simple high level interface with low level C and Cython performance. PyWavelets is very easy to use and get started with. Just install the package, open the Python interactive shell and type: Voilà! Computing wavelet transforms has never been so simple :)
