Homework 8


Date Assigned: Wednesday, October 12, 2011
Date Due: Monday, October 24, 2011

  1. Reading: In the Ulaby/Maharbiz text, please continue to study Chapter 4, Sections 4-1 through 4-7.

  2. Labs: Lab 4 will be held on Thursday, Oct. 20.

  3. We will not have class on Wednesday, Oct. 26. Homework 9 will be due on Monday, Oct. 31.

  4. Please solve the following problems in Chapter 4 of the textbook and submit solutions in class on Monday, Oct. 24.
    Problems 4.9, 4.11, 4.12, 4.13, 4.20, 4.21, 4.25, 4.26, and 4.27.
    Use the ideal op amp assumptions in all of these problems. When a value is given for Vcc, the op amp is supplied with +Vcc and -Vcc. In these problems, assume that the op amp output achieves the entire range from -Vcc to +Vcc. Real op amps are limited to a smaller output voltage range, as you observed in Lab 4.

    You should solve the problems using circuit analysis instead of matching with a "standard circuit" and using a formula from the textbook. (However, if you can match with a standard circuit, you may want to check your result.) None of the problems require solving simultaneous equations. Look for voltage dividers to simplify the analysis.

Thank you.
