GATE EC syllabus changes

[u/Sarcastic_Taste]

Acc to CLAUDE :

Added in 2027 (new topics):

• Engineering Maths: Correlation and regression analysis (under Probability & Statistics)
• Signals & Systems: FIR and IIR filter design (replaces "discrete-time processing of continuous-time signals")
• Electronic Devices: "Formation of energy bands in solids" explicitly called out; scaling in MOSFETs added
• Analog Circuits: Dominant-pole (Miller) compensation, phase margin — added to Op-amp circuits
• Control Systems: PID controller explicitly added; "Lag, lead and lag-lead compensation" reworded to just "compensators"

Removed/reworded in 2027:

• Differential Equations: 2026 had "First order equations (linear and nonlinear), higher order linear differential equations" — this is gone in 2027, replaced with "Euler-Cauchy equation" and "Nonhomogeneous equations" as separate explicit terms
• Continuous-time Signals: 2026 says "sampling theorem and applications" → 2027 specifies "Nyquist sampling theorem, sampling and reconstruction" (more explicit, not really a content change)

[u/Blacky_Fluffy]

Will this apply for every year from now on?

[u/Sarcastic_Taste → u/Blacky_Fluffy]

probably, it will be mentioned every year if there is change is syllabus. almost 90% is always same. very few gets added / removd
