Continuous wavelet transform

../../../../_images/fourier.svg

Decompose a signal into multiple different scales/frequencies and show how that frequency component of the signal varies over time.

Documentation

Continuous Wavelet Transform (CWT) is similar to Short Time Fourier Transform in that it reveals the frequency contents of a signal, and also shows how that frequency content changes over time.

Configuration

Rescale output (rescale)

Multiplies each scale output with 1/scale as a normalization

Number of scales (scales)

Number of scale values to generate, always start at scale 1
