13–23 An RC series circuit is driven by the following periodic source:

vsðtÞ = 10 cos 10 kt + 5 cos 30 kt + 3:33 cos 50 kt V

(a) Find the output taken across the capacitor when R=50 Ω

and C =5 μF.

(b) Simulate the output using Multisim and compare it to the input when C varies from 0.1 to 10 μF. Perform a “Parameter sweep” analysis on the capacitor over that range using a decade sweep, 2 points per decade. Comment on the output waveform, vis-à-vis the input. What function is the circuit performing?
