Open Signals and Systems Laboratory Exercises
Open Signals and Systems Laboratory Exercises is a collection of lab assignments that
have been used in EE 224: Signals and Systems I in the Department of Electrical and
Computer Engineering at Iowa State University. These lab exercises have been curated,
edited, and presented in a consistent format to improve student learning.
The first lab exercise introduces students to the MATLAB environment and language
with an emphasis on signal processing applications. Students solve a system of equations,
manipulate complex numbers, vectorize an equation, and manipulate sound and image files.
The next lab exercise reinforces the concepts of period and frequency by having students
record the sound of a tuning fork and measuring characteristics of the audio signal. The
third lab uses the impulse response of a system to simulate how things sound in different
locations.
