Consider the following simple RC circuit which resembles a lowpass filter (LPF). Assume unit values for the capacitance and the resistance, and the input v, (t) = cos t. a) Find the response vo(t) using the differential equation approach. b) Repeat (a) using the Laplace Transform Method. c) Repeat (a) using the Phasors method. Note: The Phasors method provide only the steady-state solution (Forced Response)! V, -/9
