If you are interested in software field than you can choose ECM. Any further information please read this article you will know more about them.

B.Tech ECM- The main objective of ECM programme is to make the UG students equipped with required employment skills in both Software and Hardware industries. The present discipline of ECE deals with Hardware related aspects and Communication aspects in which Signal Analysis, Processing, Communication theories occupy major part of the curriculum. The courses like Signals & Systems, Digital Signal Processing, Probability Theory & Stochastic Processing, Micro Wave Engineering, Analog Communications, Digital Communications contribute to this knowledge. Though this programme is very good for the candidates intending to go for hardware industry and communications industry, it is not helping much to the student who are aspiring career in software industry.

HOPE THAT'S HELPFUL

Best of luck
