3.1 The excitation of the network is the voltage of the voltage-source, while the response is the indicated i current. Give the expression of the transfer characteristic of the system (as a quotient of jw polynomials). (1.5 points) 3.2 Sketch the Bode-plot and the Nyquist-plot of the transfer characteristic of the system. (The plots can be applied if the value of the amplitude-, and phase-characteristics belonging to any angular frequency can be read from the figure.) Show the transfer characteristic vector belonging to the angular frequency of 3.3. on the Nyquist-plot, and give the values of the amplitude-, and phase-characteristics read from both plots. (1.5 points) 3.3 Calculate the peak value and the initial phase of the response, and find the time-function of the response if the excitation is: (1 point) A, cos(1,3wt + 50°) 3.4 Find the average and the reactive powers of the two-pole noted in the figure and connected to the response (marked by continuous line), and calculate the power-factor. (1 point) 3.5 # Draw the Norton equivalent of the two-pole the powers of which were asked in the previous point. Find the parameters of this equivalent. If it does not exist, find the other equivalent. 3
