1. The problem statement, all variables and given/known data Using the approximate triangular output shown and Vdc previously calculated, use the expression Vout=Vdc + Vac to solve for Vac. Find an expression for Vac that is valid from t=0 to t=T. Your expression should be in terms of Vp,R,C,T and t. The circuit is a half wave rectifier with a capacitor. Eventually I am trying to calculate ripple factor but I need the Vac to calculate Vrms and then onto calculating ripple = Vac rms / Vdc 2. Relevant equations Vdc= Vp - VpT/2RC where Vp= voltage at peak Vout=Vdc + Vac 3. The attempt at a solution I am not sure what I am supposed to be using for V out. I was given Vin=Vocosωt where T=2∏/ω is the period of the input signal. Am I supposed to use Vpcosωt for my Vout?
