Post questions or requests for clarification to the discussion page.

Previous Tests

Previous ECE 382 tests are available at Dr. G's Big Box of Random.

Review from Class

The slides from the class on Monday are available as PDF

IMPORTANT NOTE!

Test I 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 382/Spring 2010/Test 1/RSR each day until Noon the day 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 I Spring 2010 Coverage

This test comes primarily from Chapter I and Chapter II

  1. Differential equations: know how to set up nth order and solve first and second order differential equations by hand using classical methods. If there is a portion by hand, the forcing functions will be constants, exponentials, and/or polynomials up to order 2.
  2. Laplace transforms: be able to use the MOAT forwards and backwards and be able to solve simple partial fraction expansion problems. Be able to find the Laplace representation of differential equations with non-zero initial conditions and to write differential equations based on transfer functions.
  3. Circuits: be able to use the Mesh Current method to find equations for mesh currents in planar circuits. You should be able to express the equations in the time and frequency domains.
  4. Translational systems: be able to find the equations of motion for a translational mechanical system involving springs, masses, dampers, and viscous friction. You should be able to express the equations in the time and frequency domains.
  5. Rotational systems: be able to find the equations of motion for a rotational mechanical system involving torsional springs, inertias, rotational dampers, and rotational viscous friction. You should be able to express the equations in the time and frequency domains.
  6. Gears: be able to find the equations of motion for systems involving gears - note that the gears may be rotation-to-rotation or rotation-to-translation.
  7. Electromechanical: be able to use the equation for a potentiometer to relate an electrical system to a rotational mechanical system.
  8. Motors: be able to determine the transfer function for a system involving a DC motor but not involving springs; also be able to determine motor parameters if given sufficient information such as stall torque, no-load rotational speed, and the like.
