Document Summary

Problem set #10 (total 4 problems: 5 pts each) P 1 the circuit shown in figure p 1 has two inputs: v1(t) = 50 cos (20t 75 ) v v2(t) = 35 cos (20t + 110 ) v. When the circuit is at steady state, the node voltage is v(t) = 21. 25 cos (20t 168. 8 ) v. Represent the circuit in the frequency domain using phasors and impedances. Using the given equation for v(t) we get. P2 determine the thevenin equivalent of this circuit when vs(t) = 10 cos (10,000t-53. 1 ) v. P 3 the input to the circuit shown in figure p 3 is the current source current is(t) = 36 cos (25t) + 48 cos (50t + 45 ) ma. We will find the response to each of these inputs separately. Let ii(t) denote the response to isi(t) for i = 1,2.
