The pattern of xam was so simple & scoring for those who have also prepared for GATE.

A max. Number of questions were asked from Antenna, Microwave& EMFT, apart from this main concerns were Digital Electronics, fundamental question on Maths (integration & prob) were asked.

Basically all the questions were either based on formulas or simple logic. I have attempted approx. 60 − 65 questions, osme of them are as given below:

1-SNR is defined as: 4 options.

2-To calculate the number of RAMchips for a given one: 4 options
