Subject-wise Syllabus
Section I
Section I is focused on the basics of electronic engineering.
- Structure and properties of electronic engineering materials, conductors, semiconductors, insulators and magnetic materials
- Carier statistics, mechanics of current flow, junction theory and different types of diode
- Network analysis techniques, network theorem, transient and steady state responses and elements of network synthesis
- Transmission lines, standing waves, basics of waveguides and resonators and antenna theory
- Electronic measurement and instrument station basic concepts, error analysis, measuring instruments and basics of telemetry for industrial use
- Power semiconductor device (SCRs, MOSFETS), converters, regulators and pulse with modulation
Section II
It is focused on applied engineering and systems. Candidate must pay special attention to the communication system and microprocessor.
- Transistors biasing, small signal analysis, power amplifiers, oscillator and pulse shaping circuit
- Boolean algebra, logic gates, combination and sequential logic circuits and semiconductor memories
- Transient and steady state response of control system, stability analysis and design of control systems
