I've built a simple half-wave rectifier using the following components.
1 kHz sinusoidal source
I'm measuring the voltage across the resistor with an oscilloscope.
This is the wave I get with the source set to a magnitude of 1.5 V:
Bust as soon as I increase the magnitude of the source above 3.0V, this starts to happen. \
Can anyone explain what is happening here? Is this expected behaviour, or have I made a mistake?
