This course provides a comprehensive study of sensors and signal conditioning systems with a focus on applications in mechatronics and robotics. It covers the design and analysis of sensor-based input mechanisms, signal processing, and instrumentation techniques essential for modern engineering systems. Topics include sensor technologies, analog and digital signal conditioning, operational and instrumentation amplifiers, sensor interfacing, error analysis, and measurement system architecture. Emphasis is placed on integrating sensor data into mechatronic and robotic systems, with a strong focus on project-based lab work where students apply concepts in real-time control systems, preparing them for practical, real-world applications. Prerequisite: EL-200. (2-3-3)
