Electronics engineering has many subfields, including signal processing, telecommunications engineering, control engineering, instrumentation engineering, computer engineering and Very Large Scale Integration (VLSI) design engineering. The Electronics and Communications Bachelor of Technology (B.Tech.) course is very similar to the Electronics Engineering B.Tech. course. They differ only in that the former has subjects that focus more on communication engineering. Communications can be analog or digital.

Electronics and communications engineering (ECE) deals with the design and development of electronic circuits, equipment and machines. Electronic equipment and communication equipment has interconnected everyone in so many ways, such as through mobile phones, TVs, computers or iPads. Electronics is the technology associated with electronic circuits and systems, and is one of the major fields that comes under electrical engineering.
