Repo contains source code for creating and filtering EEG data from periodic, non-sinusoidal and non-stationary tCS artifacts using weighted comb filters.
Includes also code for artifact removal using adaptive DFT and adaptive PCA, and for simulation of tACS recordings.
This module is shared under a X11 license. Its development is supported by the BMBF: FKZ 13GW0119.

Artifacts can be non-stationary and non-sinusoidal, but are required to be periodic. Comb filters natively support only frequencies which are integer divisibles of the sampling frequency. This can be circumvented by resampling the signal, and has been implemented.
