    I need some help with this question:
    a. Derive an expression for the phase shift of the circuit below

    b. Calculate the phase shift at a frequency of 30 KHZ given that:
    L = 12 mH
    R = 220 ohms
    C = 47 nF
    RL = 1.2 K*ohms

    c. What is the effect on output signal amplitude and phase of open circuiting the load? See attachment.
