  2. Robert H. Bishop, Learning with Labview, Addison-Wesley

Computer Use: Students are required in homework and laboratory assignments to write substantial programs in Labview.

Laboratory Projects:

  1. Event timing and digital interfacing
  2. Instrumentation amplifiers
  3. A/D
  4. D/A
  5. A/D and Least Square Fitting
  6. Frequency Aliasing

Engineering Design Statement:
In homework, the students are given an opportunity to design interfacing circuits with many possible answers. The students carry out eight organized laboratories aimed at learning the use of the equipment and some basic circuit designs. The students will work in groups of two. By the end of the quarter each lab partner will have written four technical reports on four laboratory exercises. An open-ended two week design project is part of the course. Each team will prepare a technical report on the design project. The midterm and final exams will pose problems that require knowledge of design principles and techniques.

Professional Component: Engineering Depth, Laboratory, Project
Engineering Science: 2 units
Engineering Design: 2 units

Overlap statement: MAE 176 and EBS 165 cover some of the same topics, but these courses are based on different prerequisite material and hardware/software systems and cover applications specific to the associated disciplines.
