The voltage shown in Figure is called a square wave. The Fourier series approximation to this function is

Suppose this voltage is applied to a series RC circuit whose transfer function is
Vo(s)/Vs(s) = 1/(RCs + 1)
where R = 103Ω and C = 10-6 F. Keeping only those terms in the Fourier series whose frequencies lie within the circuit's bandwidth, obtain the expression for the steady-state voltage vo(t).
