Studyloaf's GATE Electronics and Communication posts and practice, grouped by the subjects of the official GATE 2027 EC syllabus. Each post takes one narrow question, answers it first, and works it through with real numbers and labelled diagrams.
Circuit analysis, sinusoidal steady state, transients with the Laplace transform, and two-port networks. GATE 2027 EC syllabus, Section 2: Networks, Signals and Systems.
Energy bands and carriers, carrier transport, and the P-N junction, BJT, MOSFET and optoelectronic devices. GATE 2027 EC syllabus, Section 3: Electronic Devices.
Diode circuits, BJT and MOSFET amplifiers and their frequency response, current mirrors, differential amplifiers and op-amp circuits. GATE 2027 EC syllabus, Section 4: Analog Circuits.
Number representation, combinational and sequential circuits, timing, data converters, memories and computer organization. GATE 2027 EC syllabus, Section 5: Digital Circuits.
LTI systems, Fourier series and transform, sampling, and discrete-time signals with the DTFT, DFT and z-transform. GATE 2027 EC syllabus, Section 2: Networks, Signals and Systems.
Transfer functions and block diagrams, transient and steady-state response, stability criteria, Bode and root-locus plots, compensators and state equations. GATE 2027 EC syllabus, Section 6: Control Systems.
Random processes, analog and digital modulation, information theory, detection, and error correction. GATE 2027 EC syllabus, Section 7: Communications.
