### GATE Analysis for EC by GATE Forum – Forenoon Session (3)

As per the experts, the GATE 2017 Question Paper for EC was formula based. Compared to last year, more questions were asked from Digital Circuits and Signals System. Whereas, the weightage of Communications and Electromagnetic has decreased a little. In all, the paper was moderate in difficulty and in comparison to last year, it was easier.

The subject distribution of 1 and 2 marks question is as below:

 Subjects Topics 2 Marks 1 Marks Total Questions Engineering Mathematics – 5 4 9 Networks AC analysis, transient analysis, Basics of networks 2 1 3 Electronics Devices Diodes, Region of operation, diffusion and drift current 4 3 7 Analog Circuits Op-amp, Miller capacitance, Schmitt trigger 3 3 6 Digital Circuits Sequential circuits, FSM, Boolean algebra, Microprocessor (8085, instruction set) 4 3 7 Signals and Systems LTI systems, Fourier series, Continuous time Fourier transform 4 4 8 Control Systems RH criterion, steady state error, TDA, Nyquist plot, compensator 3 3 6 Communication ISI, random variables, DBCM, FSK 2 3 5 Electromagnetic Polarisation, wave equation, optical fibre, radars 3 1 4 Verbal Ability – 1 3 4 Numerical Ability – 4 2 6 Total 35 30 65
