 - [X] **Data Filtering** : We will be adding bio-potential signal filtering options which includes 50/60 Hz notch filter to remove AC interference noise and highpass/lowpass remove artefacts from ECG, Emg ,Eog and EEg. Under filters, we will be adding different highpass and lowpass filters for specific bio-potential signals this feature will further enhance the user experience to record even more clear biopotential signals.
