Hi Shireesha,
It depends upon the category as well. If you are General category candidate then 2800 rank is not enough. If you are SC/ST/OBC or other category, you may still have chances. There are only 25 seats for M.Tech in Digital Electronics & Communication Systems so cut offs are generally high.
Thank you and best of luck.
