CE 3101 - Digital Electronics and Computer Interfacing3 lecture hours 2 lab hours 4 credits
Digital electronics are diode and transistor circuits that operate on digital signals. This course introduces the design and analysis of diode circuits, BJT circuits, and MOSFET circuits with a focus on digital logic families. It also examines electronic circuits commonly used to interface sensors or actuators to the computer. Interfacing topics include analog-to-digital signal conditioning using operational amplifiers, digital-to-analog conversion using standard solid-state components, and large-signal biasing of BJT and MOSFET drivers.
