Suggestion: AC mode through digital filtering #8

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
Wouldn't it be possible, and relatively simple to implement a simple high-pass 
digital filter (say, an IIR or a FIR digital filter) to add an AC mode to the 
oscilloscope (to filter out the DC level)?
That possibility must have been considered before, but what stood in the way of 
implementing it? I can't seem to compile and upload the code (all the guides 
for that are offline on the wiki) but I can try to help with the filter design 
if needed.
