This course includes introductory knowledge of analog and digital communication systems, aimed at undergraduate students majoring in electrical and computer engineering.

This package contains course materials for an introductory analog and digital communications systems course taught to undergraduate electrical and computer engineering students.

An integral part of the course design is a series of laboratory modules through which students explore course topics using low-cost SDR hardware (e.g., RTL-SDR or ADALM-PLUTO) and MATLAB/Simulink software tools.

Using these laboratory exercises, students implement various communication systems and investigate real-world communication signals.
