Homework 7

Date Assigned: Monday, February 28, 2005
Date Due: Monday, March 7, 2005 ** CHANGED TO Wednesday, March 9 **

Please hand in your lab notebooks on Thursday, March 3 so that I can grade Labs 1-5.

  1. Reading: The relevant reading is in Sections 3.1, 3.2, and 3.3. We will not cover every topic in the text, and we will emphasize capacitors more than inductors. The concept of a time constant is very important.

  2. Please solve the following problems in Chapter 3 of the Bobrow text.

  3. Please solve problem 3.48 in the text. Note that the voltage source has value 0 volts for t < 0, and V volts for t >= 0. Thus it is equivalent to "closing a switch" at time t = 0 to connect an ideal source with value V volts.

    Hint: Write KCL at the "-" input of the op amp. Use the ideal op amp assumptions.

    Also answer the following questions for this circuit.

  4. Please analyze the RC circuit that we used in Lab 6 for the following cases. Assume that Vs = 12 V, C = 1 microfarad, R = 1,000 ohms, and Rs = 100 ohms.
Thank you.
