Mmm. And this  we 've not uh worked on this yet. Um , yeah. And so while discussing about these  these LDA filters , some i issues appeared , like well , the fact that if we look at the frequency response of these filters it 's uh , well , we don't know really what 's the important part in the frequency response and there is the fact that  in the very low frequency , these filters don't  don't really remove a lot.  compared to the  to the uh standard RASTA filter. Uh and that 's probably a reason why , yeah , on - line normalization helps because it  it ,
Right.
yeah , it removed this mean. Um. Yeah , but perhaps everything could  should be  could be in the filter , I mean , uh the  the mean normalization and  Yeah. So. Yeah. So basically that was  that 's  all we discussed about. We discussed about  good things to do also uh well , generally good stuff  to do for the research.
Mm - hmm.
