Day 7: Time Varying Signals

This is the set up for a BJT curve tracer. It contains two voltages that vary differently as they have different effects on each other as they travel through the BJT.

This is the effects of a change in the resistance on the circuit. The wavelength is constant but the amplitude is decreased.

This is a closer look at the BJT Curve Tracer set up. It has one voltage source that is DC and the other is a step voltage source.

This is the set up of the circuit. The graph is what is expected to see from the voltage out of the transistor.

This the view of the voltage coming from the waveform and the oscilloscope measuring the output.

Using a triangle voltage supplied from the wave form, the oscilloscope measures a triangular wave output.

This waveform uses a sinusoidal wave.  The oscilloscope measures a sinusoidal wave.
This is the graph as the voltage is stepped up and it reaches its limit across the transistor.
