Ok so my teacher gave us this as an assignment: and was tasked with drawing the output voltage. The input voltage is a sine wave with 10v and -10v as its peaks. So I know that the positive cycle will have both diodes be forward biased and the negative cycle will have 3 parts. First is when Vin<2v, both diodes are forward biased; Second is when 2v<Vin<5, D1 is reverse biased and D2 is Forward biased so Vo=-5v; And the last part is when Vin>5v, both diodes are reverse biased so Vo=Vin. Now what confuses me is when both diodes are forward biased so the diodes turn into a short, leaving 2 cells with different voltages in parallel which I don't think is good/posibble. If it is ppossible then I'm not sure what is Vo is. I'm thinking it's -5v, -3v or -7v. Anyways, can someone help me out here?
