DSPPeriodogram and coherence in frequencies <1Hz
Thu, 11/08/2018 - 06:34 am
I was wondering if anyone knows of a way to set the frequency resolution of DSPPeriodgram function? I'm trying to look at coherence of an EEG signal across different brain regions, and how this changes in a model of dementia. However, I'm interested in a slow oscillation that peaks around 0.2 to 0.8Hz, so ideally I would be able to resolve coherence in 0.2 to 0.25 Hz bins, which I can't seem to do with the DSPPeriodgram function.
Thanks in advance!
