1. The problem statement, all variables and given/known data We have the circuit in the figure.I have to find the output graphically if the input is Vi=15sinwt. 2. Relevant equations This type of exercise doesnt have any equations 3. The attempt at a solution Heres the circuit http://i.imgur.com/ivixWzH.jpg For Vi<= -10 the diode is ON and Vo=10 10<=Vi we have that the diode is OFF and Vi=Vo My solution is this one : http://i.imgur.com/ZMUB66j.jpg Is it correct ? How can I find the output numerically in exercises like this?
