    Images attached of what ive tried to do and link to the document that everybody puts up

    the following are steps we need to do.

    1 - Find Vx
    2 - Using Vx find Vout/Vin which is equal to H(w) this is what we really need
    3 - Using the new formula we just found H(w) convert it to G(w) bu using complex/real/imaginary numbers also called formula for scalar amplitude of the transfer function
    4 - with this new formula plot it for different frequencies
    5 - a few easy questions if the rest can be done

    If we do manage to solve it someone might like to start a thread with how they went with prac 8 and what formulas they used.
