    I hope that I'm not disturbing you with a similar question again.
    I just wanna make sure I am correct on this one.
    I have to find:
    • Output Waveform
    • V_{AVG}

    Here's the circuit:

    V_o terminals are as usual.

    V_i=6sin(\omega t)

    V_i>2V, D1 ON, D2 OFF, V_o=3sin(wt)+1
    V_i<-4V, D1 OFF, D2 ON, V_o=-4V
    -4\leq V_i \geq 2V, D1 OFF, D2 OFF, V_o=V_i

    * V_o waveform:

    * V_{AVG}:
    which gives as a result V_{AVG}=-0.155847
    Am i right ? Im not sure because this is the most complex waveform I solved.

    I see that you found Mathematica, presumably on your school's network.

    I solved the problem using the simpler method I demonstrated in the other thread. I get exactly the same result, so you're good to go. :)
