About Course
Digital Electronics is the study of electronic circuits that are used to process and control digital signals.
In contrast to analog electronics, where information is represented by a continuously varying voltage, digital signals are represented by two discreet voltages or logic levels. This distinction allows for greater signal speed and storage capabilities and has revolutionized the world’s electronics. Digital electronics is the foundation of all modern electronic devices such as cellular phones, MP3 players, laptop computers, digital cameras, high definition televisions, etc.
The major focus of the DE course is to expose students to the design process of combinational and sequential logic design, teamwork, communication methods, engineering standards, and technical documentation.
Digital Electronics is one of three foundation courses in the Project Lead The Way
high school preengineering program. The course applies and concurrently develops secondarylevel knowledge and skills in mathematics, science, and technology.
