ECE 141/Spring 2010/Test 2
From PrattWiki
This page is the review sheet for Test II for ECE 141 in Spring 2010; post any questions or requests for clarification to the discussion portion of this page (see tab above).

Previous Tests
Previous ECE 141 tests are available at Dr. G's Big Box of Random.
IMPORTANT NOTE!
Test II this year is closed-book and will not have a computational component to it. Though you will be taking the test in the lab room, that is primarily so you have extra time to complete the work.
Equation Sheet
The class will come up with an equation sheet. Post the equation that you would like to the discussion page of this article; I will generate the list of approved and disapproved equations at ECE 141/Spring 2010/Test 2/RSR each day until Noon two days before the test, at which time the equation sheet will be set. The actual equation sheet will be available by 11:59PM the day before the test; a copy will be handed out with the test as well.
Test II Spring 2010 Coverage
Chapter III
- Set up state space equations for electrical, mechanical, and hybrid systems.
- Set up phase space equations from a differential equation or transfer function.
Chapter IV
- Determine characteristics of the step response for a first-order system or design a system to achieve those characteristics. Specifically, rise time and settling time.
- Determine the characteristics of the step response for a second-order system or design a system to achieve those characteristics. Specifically for a second-order underdamped system: rise time, peak time, %OS, settling time, damping, natural frequency, and damped frequency.
- Know when extra poles and zeros interfere with the assumptions of a dominant pair of poles.
Chapter V
- Translate a block diagram into a signal flow graph.
- Determine the transfer function of a signal flow graph.
Chapter VI
- Generate a Routh array for a transfer function and determine regions of stability. Be sure to know how to handle rows with all zeros and rows with leading zeros.
- Find the value of one or more free parameters to obtain marginal stability and the frequency of oscillation for marginal stability.
Chapter VII
- Find system type, static error constants, and steady state error for unity feedback systems.
- Determine equivalent forward transfer function for systems not fitting the unity feedback paradigm, and find system type, static error constants, and steady state error for those systems.
- Design a system satisfying both stability and error considerations.
Specifically Not On The Test
- Maple
- MATLAB
- Root Locus
