I'm wanting to use the DC-block block, and I have questions about its use.
My scenario is to use it as a cheap high-pass, with a corner frequency of a
few milli-hertz, with samples arriving at 50Hz.
It's not clear how the "length" parameter relates to the desired corner
frequency and sample rate.
I believe this is implemented as described as a linear phase DC
blocker in this paper:
http://www.digitalsignallabs.com/dcblock.pdf
I believe the "length" parameter is the "D" parameter in the moving
average calculations.
Hopefully this helps.

Thanks muchly. This helps a lot.
The graph at 4(a) is quite enlightening.
