Linear Circuit Analysis:
Introduction

In this field, several areas of the functionality of the TI-92 are utilized. These include, but are not limited to:

• The Computer Algebraic Operating System for solving equations symbolically.
• The extensive graphing features, including the capability to graph and perform mathematics operations on piecewise-defined functions.
• The Text Editor to call equations to the home screen for instant evaluation. Also, the Text Editor is used as a handy place to store formulas used with these examples.
• The adv.92g group available from the Program Archives or Soft Warehouse for the use of solving first order differential equations.
• The use of user defined functions and programs for help in solving circuit type problems, as well as adding to the TI-92's functionality.

All of the user defined functions and programs are available at the Program Archives in a group file named circuits.92g. Where possible, the code for the user defined functions is shown in the form of a TI-92 screen shot. Some of the programs, however, were too large to show in this manner.

In a recent discussion an Electrical Engineering Professor stated that teachers do not have enough time to provide students with worked examples. He went on further to say that students really need to learn to use their calculators to their fullest potential in order to understand all of the material that is covered in a course as intensive as Linear Circuit Analysis. These pages help provide a solution to these problems as well.

These pages assume two things from the reader. First, either the reader is taking or has taken a course in Linear Circuit Analysis. Second, the reader has a basic knowledge of the TI-92 operating procedures and calculus concepts.

These pages were written by an Electrical Engineering student for Electrical Engineering students. If you are taking a linear circuit analysis course, you are strongly encouraged to edit the text file and write additional user-defined functions and programs. You can then incorporate them into the custom menu along with other functions (yours or others) for easier accessibility. This will help you become more proficient with the use of your calculator.

While these pages are fairly extensive, they by no means cover every topic that an EE professor could ask. Like any other class, this subject requires practice. Follow along with the problems with calculator, pencil, and paper in hand, then use these examples to do similar types of problems.
