Hi, I'm trying to figure out why the output voltage waveform of this circuit would not include a DC offset of E. My understanding is that D1 becomes forward biased when Vs > E, and so that is when it should conduct. Every waveform drawing I've seen, on the other hand, begins conduction at 0...

Yeah, I'm not sure what the point of including that was. The problem statement I posted originally is exactly the same as given - furthermore, this is an old exam question, so I doubt it's a mistake. I guess the main problem here is figuring out what the switch changes (though I've even put it...
