hi muhammed,

You have two branches as a specialization after GATE ECE in IIT Mandi

These 2 are:

• Electrical Engineering with specialisation in VLSI
• Signal Processing and Communications

According last year(2019) cutoff:

VLSI: 618

Signal Processing and Communications: 503

You can get Mtech course in signal processing and communication in IIT Mandi.

I hope this answer will help.
All the best for the future!!
