Why Previous Year's Question Papers Are Essential?

Previous year question papers are essential to know the pattern of an examination. You should go through at least the last 10 years' question papers before sitting for any examination.

UGC NET Electronic Science (Code 88) Exam Overview

The UGC NET Electronics Science examination consists of two papers. Paper 1 covers General Teaching & Research Aptitude, while Paper 2 focuses specifically on Subject Code 88. To succeed, candidates must master topics such as:

  • Semiconductor Devices & IC Fabrication
  • Network Theory and Signals & Systems
  • Digital Electronics and Microprocessors (8085/8051)
  • Electromagnetics and Antennas

Using previous year question papers is the most effective way to understand the weightage of these topics.

📈 Topic-wise Weightage Analysis

Based on 2023-2024 trends, here is the approximate number of questions asked from each module:

Semiconductor Devices: 12-15 Questions
Digital & Microprocessors: 10-12 Questions
Electromagnetics (EMFT): 8-10 Questions

🎁 Bonus: UGC NET Paper 1 Resources

Don't ignore the General Aptitude paper! It carries 100 marks and is key to securing JRF.

Q-function in BER vs SNR Calculation

Q-function in BER vs. SNR Calculation | Interactive Guide Q-function in BER vs. SNR Calculation In digital communications and signal processing, the Q-function plays a significant role in predicting system reliability. It allows engineers to quantify the probability that Gaussian noise will exceed a specific threshold, causing a bit error. What is the Q-function? The Q-function is a mathematical function representing the tail probability of the standard normal (Gaussian) distribution. It is the complementary cumulative distribution function (CCDF) of a standard Gaussian distribution. Q(x) = (1 / √(2π)) ∫ₓ∞ e^(-t² / 2) dt Q-Function Interactive Simulator Move the slider to see how the "Tail Probability" (the area in red) changes.

DFTs-OFDM vs OFDM: Why DFT-Spread OFDM Reduces PAPR Effectively (with MATLAB Code)

Understanding PAPR in DFT-spread OFDM vs. Standard OFDM In modern wireless communications like 4G LTE and 5G NR, managing the Peak-to-Average Power Ratio (PAPR) is critical for hardware efficiency. While OFDM is the gold standard for high-speed data, its high PAPR poses significant challenges for mobile devices. This is where DFTs-OFDM (also known as SC-FDMA) comes in. DFT-spread OFDM (DFTs-OFDM) has lower Peak-to-Average Power Ratio (PAPR) because it "spreads" the data in the frequency domain before applying IFFT, making the time-domain signal behave more like a single-carrier signal rather than a multi-carrier one like OFDM.

Which of the following statements are correct? A. If the intermediate frequency is too high, poor selectivity results even if sharp cutoff filters are used in the IF stage.

  61) Which of the following statements are correct?  A. If the intermediate frequency is too high, poor selectivity results even if sharp cutoff filters are used in the IF stage.  B. A high value of intermediate frequency increases tracking difficulties.  C. As the intermediate frequency is lowered, image frequency rejection becomes better.  D.
