Instructions If you wish to submit a solution set to obtain my feedback on your solutions… send it to me, via E-mail: personic@adm.njit.edu The “subject” of your E-mail should be: ECE 231 HW#11 (your last name) I will provide feedback to you, via reply e- mail. I will also post a solution set on the course web site on April 17. This homework set will not be graded…

Problem 1 N turns vs(t ) 10 turns 8 Ohms ~ + Ideal transformer + v2(t) - i2(t) vs(t) 160sin(2000 π t) Volts + v1(t ) - Rs =800 Ohms In order to match the 8 Ohm load (on the right) to the source (on the left), what value should we chose for N?

Unformatted text preview: If we use that value for N: What will v1(t) be? How much peak power will flow into the 8 Ohm resistor (in Watts)? How much average power will flow into the 8 Ohm resistor (in Watts)? Thevenin equivalent circuit of the source Problem 2 Vs(t) =Vs e j t Vs= 10 Volts a b L = 10-5 H R=10 d i1(t) c i1(t) = 1 x e j t Vcd(t) = Vcd x e j t What is the frequency, fresonant , at which the impedance of the inductor = - the impedance of the capacitor? [where f= / 2 ] Calculate the magnitude of the output, | Vcd |, of this filter for the following three different input frequencies: f= n x fresonant where n= 1,2,and 3 C = 10-9 F +-R=10 Vs(t)...
