Modeling Equations

The activities in this lab demonstrate to students that the output of all communications systems can be described mathematically with equations, and that these equations can be modeled with electronic circuit blocks. Students will investigate the addition of two Sine wave signals using the Add module on the Emona Communication Board. They will investigate the output characteristic when the two input signals are the same and when they are out of phase. They will calculate the output signals and then compare the theoretical calculation with the measured signals.

This is lab 2 of 22 in the course, Communications Principles.

LEARNING OBJECTIVES


After completing this lab, students will be able to:
  1. Contrast the addition of electrical signal in relation to the math of addition.
  2. Describe the effect of phase shifts on signals
  3. Understand the relationship between math theory and its implementation with real electrical circuits.
