Fall 2011 Homework assignment 3 Due October 14, 2011 *Note: there are two prelabs on this assignment. RLC prelab (questions 1 and 2) was given with HW2, but it will be due with HW3. Question 3 is the prelab to Lab 3, and will also be due with this homework as well. Covered: Chapters 6-8: Inductors and capacitors, Natural and step responses of RC and RL circuits, natural and step responses of RLC circuits, under, over and critically damped responses. 1) Lab 2 Prelab: Consider the following RC circuit and RL circuits: a. For the RC circuit, what its time constant? b. What will the RC step response be? Hint: what are I(∞) and Vout(∞) if Vin(t)=1V·u(t)? c. For the LC circuit, what its time constant? d. What will the LC step response be? Hint: what are I(∞) and Vout(∞) if Vin(t)=1V·u(t)? 2) Lab 2 Prelab: Consider the following RLC circuit which is driven by the function generator as shown below. Note that the 50 Ω load which appears on the output of the function generator is also placed in the circuit diagram. The square wave transitions from zero to +1.0 V. a. What is the equivalent parallel resistance in this RLC circuit? b. Calculate the parameters and ω 0 for this circuit and determine the type of response which v(t) will have. Is it under damped, over damped, or critically damped? c. Calculate ω d if the circuit is under damped and then, calculate the expected period of oscillation. I(t)
