The circuit shown in figure is used to charge the capacitor C alternately from two current sources as indicated. The switches S1 and S2 are mechanically coupled and connnected as follows:For 2nT≤t<(2n+1)T,(n=0,1,2...) S1 to P1 and S2 to P2For (2n+1)T≤t<(2n+2)T,(n=0,1,2,......) S1 to Q1 and S2 to Q2Assume that the capacitor has zero intial charge. Given that u(t) is a uint step function, the voltage Vc(t) across the capacitor is given by |
