I'm working on a series RLC problem where the input voltage is a sinusoidal function for all time. The catch is, for t < 0, the sinusoidal function is of greater magnitude than t >= 0. There is no phase or frequency change.
I am okay at working DC analysis for t < 0 and then AC, but I have no idea how to do this problem.
My guess is to do phasor/fourier analysis for t < 0, and once t = 0 I could use laplace domain now that there are "initial conditions" on the inductor and capacitor, then use those voltage drops to find my final equation for the voltage across the capacitor. I don't want anybody to do my homework for me, but pushing me in the right direction would be fantastic. Thank you.
