Unformatted text preview: ECE102 Quiz 1 - Prereqs Winter 2006 2 Question 3 (2+2 points): (a) Find the magnitude and phase of X. 2 2 1 1 = j e X (b) Draw a low-pass filter using 1 inductor and 1 resistor. Question 4 (1+2+1 points): For this question, assume the opamp is ideal with infinite gain. (a) Copy the circuit on your answer pages and indicate the + and terminals such that the circuit operates correctly (i.e. in negative feedback). (b) Find the voltage V out . (c) Find the value of I 1 . Question 5 (1+2+1 points): = 10 6 rad/s. Hint: you can use phasors. (a) Find the time domain voltage v R (t) across the resistor. (b) Find the time domain voltage v C (t) across the capacitor. (c) Find the time domain voltage v out (t). You dont need to calculate the phase, only the amplitude. I 1 V in = 1 V V out R 1 = 2 k R 2 = 1 k R 3 = 1 k v out 3 0.25 F i = cos( t) A...
