EE 110, Fall 2009, Homework #1, Due October 8, 2009 Problem 1: Compute the phasors, if they exist, corresponding to the following signals. a. x(t) = 10cos(1000t – 60°) b. x(t) = 0.1sin(1000t – 60°) c. x(t) = 3sin(400 π t – 270°) d. x(t) = 3cos(50 π t – 60°) + 4sin(50 π t – 60°) e. x(t) = 3cos(400 π t – 270°) + 4sin(1000 π t – 60°) (5 x 2 = 10 points) Problem 2: Compute the sinusoidal signals corresponding to the following phasors. a. X = 3 + 4j b. X = –j c. X = 10e j π /6 d. X = 4e j5 π /6 e. X = 4e –j5 π /6 (5 x 2 = 10 points) Problem 3: Refer to the circuit schematic shown in Figure 1. a. Obtain the phasor domain representation for the circuit shown in the figure. b. Determine the value of the inductance, L, such that the steady state component of v c (t) is in phase with the voltage source. c. For L = 1mH, determine the currents through the inductor, i L (t), and the resistor, i R (t). (4 + 8 + 8 = 20 points) Problem 4: Refer to Figure 2 for this problem.
