### Purpose

Extraction of components of the wavelet transform

### Description

Extract one octave from a discrete/continuous wavelet transform
dataset (signal type DWT or CWT).
You can also extract the residue (last approximation) of a DWT by entering a number that exceeds the number of octaves contained in the
input signal.

Parameters for "Wavelet extract" are

- the octave o to be extracted
- (voice v -- not supported yet!)

### Modules
