SSC Scientific Assistant Electronics & Telecommunication Syllabus
Electronics and Telecommunication Engineering is the third Part 2 stream option. You attempt only the stream selected in your application, and attempting another leads to rejection of the candidature.
The syllabus splits cleanly in two. Electronics covers devices and circuits. Telecommunication covers how signals are sent, which is the half most directly connected to the work the India Meteorological Department does.

Electronics topics
Materials and passive components
Conductors, semiconductors and insulators. Magnetic and passive components, along with the characteristics of resistors, capacitors and inductors.
Diodes and rectifiers
PN junction characteristics, Zener diodes, rectifiers and filters.
Transistors and amplifiers
Bipolar junction transistors, JFET and MOSFET, biasing and amplifier configurations.
Circuit analysis and network theorems
Voltage and current relationships, Thevenin’s and Norton’s theorems, superposition and maximum power transfer.
Operational amplifiers
Characteristics and standard applications.
Digital electronics
Number systems, Boolean algebra, logic gates, combinational logic design, flip flops, counters and registers.
Telecommunication topics
Basics and principles of telecommunication
Signals, bandwidth, noise and the elements of a communication system.
Antennas
Directivity, radiation patterns and gain.
Wave propagation
Ground wave, sky wave and space wave propagation.
Modulation and demodulation
Amplitude, frequency and phase modulation with their demodulation techniques.
Digital communication
Sampling, quantisation, pulse code modulation, differential PCM and delta modulation.
Multiplexing
Time division and frequency division multiplexing.
Why the telecommunication half matters here
The India Meteorological Department runs a network of observation stations, radars and satellite links. Getting data from an instrument in the field to a forecasting centre is a telecommunication problem, and the syllabus reflects that.
Propagation, antennas and modulation are the topics closest to that work, and they appear more often than a candidate preparing from a generic electronics syllabus would expect. Digital electronics is the other reliable block, because it is factual and fast to answer.
How to prepare
Work from your degree or diploma notes. The standard is introductory and questions stay close to fundamentals rather than reaching design level detail.
Give digital electronics and the telecommunication half priority over deep circuit analysis. Both produce faster questions and both recur.
Previous years’ papers are the only reliable guide to depth. Use them to calibrate each topic, then stop.
Keep a formula sheet and revise it weekly. In a paper without sectional timing, recall speed is what buys you the time to finish.
Frequently asked questions
How many questions are in the electronics stream paper?
100 questions for 100 marks in Part 2.
Is digital electronics part of the syllabus?
Yes, covering number systems, Boolean algebra, logic gates, combinational logic design, flip flops, counters and registers.
Can I switch streams on exam day?
No. Attempting a paper other than the one selected in your application leads to rejection.
Which telecommunication topics carry the most weight?
Propagation, antennas and modulation, all of which connect directly to the department’s observation network.
What is the negative marking?
0.25 marks for each wrong answer.
