Oscilloscope trigger homework problem
Here is the problem.
Hopefully there's some OTFer out there who knows their oscilloscopes.
The first answer is 2.5V (not -2.5V in the picture I linked), but I'm having trouble getting ?t (for the second part)
I've just used an oscilloscope for the first time last week, and I don't know much about it. What does changing the trigger slope polarity affect in this case? Apparently the scope still triggers at 2.5V... please shed some light on me!
