The thing you need to see is that the diodes are "not there" if Vo is between - 0.7V and + 0.7V. So for that range of Vo you get just the sinusoidal output voltage 1.414sin(wt). But as soon as Vo > +0.7V or < -0.7V, Vo has to stay ("is clamped") at those voltage levels. Now try to reconstruct what Vo must look like over an entire period.servehover said:Would it go from 0 to 0.7 or -0.7 to 0.7? I really don't understand the problem(s) and neither do any of my classmates.
Yes. There is no clipping.servehover said:If there is no series resistor in my problem (it is parallel), does that mean there is no clipping in my problem?
Say your input is 1V rms. If the diode is maintaining 0.7V across it, where is the remaining voltage? It has to appear across the series resistance. That means, without the series resistance, all the voltage would appear across the diodes and there will be no clipping. If there is a series resistance, the diode almost maintains 0.7V across it and the remaining voltage appears across the series resistance.servehover said:Can you explain this?
So it'd basically be a sine wave that is cut off beyond 0.7 and -0.7.rude man said:The thing you need to see is that the diodes are "not there" if Vo is between - 0.7V and + 0.7V.

I would say yes..servehover said:So just to be confirm:
There is no series resistor in my circuit (it looks parallel). This means that the output voltage is simply 1Vrms...?
I think I will stick to 1Vrms as I have yet to find any clipping circuit on Google with parallel resistor. Can you offer any hints for the other 3 problems?cnh1995 said:I would say yes..
There being 2 possible correct answers, this is only one of them.servehover said:So just to be confirm:
