I am working on the Comedi documentation (you can peek at what I am doing at <http://people.mech.kuleuven.ac.be/~bruyninc/comedi/>, with the HTML version at <http://people.mech.kuleuven.ac.be/~bruyninc/comedi/comedi.html>, and there are quite some things I do not understand very well. Here is a first list. What exactly does the following phrase mean: "The argument is reserved and should be set to 0." (It occurs in the explanation of the TRIG_OTHER argument for a Comedi command.) In the section on "Slowly-varying inputs" it reads: "The more noise you have, the greater your SFDR, but it takes many more samples to compensate for the increased noise." I thought that more noise gave a _smaller_ SFDR, such that it requires more samples. THe first option for the flags in the comedi_cmd is TRIG_BOGUS; the comment that comes with it is "do the motions?". What does this mean? What are the exact meanings of "dithering" adn "deglitching"? What is the status of the sections that document "Status: design" features, such as counters, "Bitfield Pattern Matching Extended Trigger", etc. (I'm in the first place interested in the counter/encoder design.)
