hi!
when I send a square wave to a digital oscilloscope it detects the signal + dc signal. I wanted to know why. I was thinking about internal resistance of coaxial cable i was using.
signal got out of an oscilloscope/wave generator and in channel A of the same oscilloscope/wg. It was +-1 V, while dc component was something like 17 mV.
