The objective of this lab is to perform various experiments to consolidate basic knowledge in digital electronics. Digital IC technology advances year by year at a rate which is unimaginable for other areas of technology. But the basic knowledge remains the same. Every digital system, no matter how complex it is, is built from logic gates and flip-flops. Digital Electronics Lab provides a platform for the students to have hands on experience with digital ICs. The students will be able to have a better understanding about the concepts learned and they will gain experience in designing, testing and realizing digital circuits. The lab is equipped with digital training kits which were developed in-house.
