Teaching-Learning Methodology
Topics are taught using interactive lectures, real industrial equipment demonstrations, and short videos. Every topic is directly linked to an ME, CE, CH, or TX application. No deep semiconductor physics — emphasis is on reading circuit blocks, understanding sensor data sheets, and working with automation electronics.
