Precision, Passion, and Progress; No Instrument - No Industry

The Electronics and Instrumentation laboratory is the state-of-the-art facility that provides students with the opportunity to learn and apply the principles of analog electronics to digital logic designs and instrumentation in a hands-on environment. The laboratory is equipped with a wide range of equipment, including oscilloscopes, function generators, power supplies, digital multimeters, and various sensors and actuators. This allows students to conduct experiments and design and build electronic circuits and instrumentation systems.

The EI lab is used for a variety of undergraduate and graduate courses in DEEE. In these courses, students learn about the design, construction, and testing of electronic circuits and instrumentation systems. The lab provides them with the opportunity to develop the skills and knowledge they need to design and build innovative and effective electronic circuits and instrumentation systems. In addition to its educational role, the EI laboratory is also used for research purposes. Faculty and graduate students use the laboratory to conduct research on a variety of topics, including new electronic circuit designs, new instrumentation techniques, and new applications for electronics and instrumentation in industry and science.
