It's also important to note that all of the filters in Processing assume that the OpenBCI sample rate is 250 Hz.  If you run at a different sample rate, these hard-coded filter coefficients are all go

I wrote the filters that are in the Processing GUI.  As William suggested, I computed the filter coefficients in Matlab.  You can see the Matlab command that I used in the Processing source code...spe

But as you can see from the source, the filter coefficients were derived from another program (I think Matlab). So for example if you wanted to build another type of filter, that involves a fair amoun

And I got the following coefficients, which is exactly what you got:

Dear all,
