Silly Job Title: Surge Sage. I am the Surge Sage!

In this video we continue working through Learning the Art of Electronics. Today we build a differentiator with a resistor and capacitor and test it with a square wave and a sine wave.

We use the Rigol MSO5074 Mixed Signal Oscilloscope to investigate our signals and to generate our input waveforms.

We use the Multicomp Pro MP701033 Resistor Decade Box as our variable resistor.

We use the Kaisi S-160 45x30cm Repair Mat as our workspace.
