How does an O-scope measure multiple waves with one probe?
How does an O-scope measure multiple waves with one probe?
(OP)
I recently saw something on an oscilloscope that made me wonder how an oscilloscope works. It was a step function, with each step boxed off, having 4 sides. Plus there was a diagonal line inside each box.
The way I understand it, a digital O-scope would sample the probe and should only find 1 voltage. So the scope should read a continuous line. If multiple signals are on one line, then the scope should display the sum. How could the scope display 3 different voltages at one time? I have seen this type of thing before, but never thought about it.
Attaching a snip of a bad picture I took of the scope with my phone.
