Discrete wavelet tranformation
==============================

Transformation derived from wavelet transform for discrete wavelets. Computes approximation and deail coefficient.

**Inputs**

- [Epochs](https://mne.tools/0.17/generated/mne.Epochs.html)

**Outputs**

- [numpy.ndarray][1]: Approximation coefficient
- [numpy.ndarray][1]: Detail coefficient
