Today, I remeasured the transfer function for MC2 to MCL in order to improve the subtraction performance for MCL and to quantify just how precisely it needs to be.
Here is the fit, and the measured coherence. Data is also attached here: TF.zip
OMG, I forgot to post the data and any residuals. LOL!
The transfer function was fitted using vectfit with a weighting based on coherence being greater than 0.95.
I then used the following filters to do FF on MCL online:
Here are the results:
Performance has definelty increased when compared to previous filters. The reason why I think we still have poor performance at 3 Hz, is 1) When I remeasured the transfer function, Eric and I were expecting to see a difference on its shape due to the whitening filters that were loaded a couple days ago. 2) Assuming the transfer function is correct, there is poor coherence at 3 Hz 3) The predicted IIR subtraction is worst at this frequency.
