#232: More Circuit Fun: Simple transistor curve tracer using Stairstep generator circuit

This video builds upon the previous "Circuit Fun" video that presented at simple stairstep generator: https://www.youtube.com/watch?v=Kqb5zcrgv7s It uses the stairstep waveform and one of the pulse signals, along with a little additional circuitry to create a very basic curve tracer for NPN transistors. It can be used to plot the collector curves of NPN transistors (Ic vs Vce at different base currents). Since the circuit is very basic, the curves aren't perfect, but it certainly works well enough for basis transistor testing and matching.
