Sedra & Smith (S&S): Chap 3 Thomas & Rosa (T&R): Chapters 7-8 Homework #2
1) 2) Do problem 7.12 in T&R Due: Friday 26 January 2007 L For the second-order circuit at right, do the + following: Vin a. First, find the differential equation for C R Vout Vout (t ) b. Find the roots of the characteristic equation assuming L = 10 nH , C = 50 pF , and R = 1 . Is this over-damped, under-damped, or critically damped? c. Assuming a step-function stimulus Vin (t ) = u (t ) , find and sketch the output response Vout (t ) d. Repeat for R = 100 3) 4) 5) Do problem 7.36 in T&R Do problem 7.40 in T&R The circuit shown uses an ideal transformer with a turns ratio of 1:2. Find the output voltage if the input voltage is Vin Vin = 16cos 5t . Do problem 3.72 in S&S (show your work) Do problem 3.76 in S&S (show your work)
