Physics - Communication System

Practise 8 VITEEE previous year questions on Communication System, compiled from papers spanning 2006 to 2023. Each question is pulled directly from the actual exam paper it appeared in, so you're practising in the exact style and difficulty VITEEE tests.

Communication System has been asked in 6 of the 18 years of VITEEE papers analysed (2006–2024), with 8 questions in all. 88% of them were easy, 13% moderate and 0% tough. Most of its questions came from 2011, with 2 questions that year. In the last three years (2022–2024) it had 2 questions across 2 papers, about 1 per paper.

The chapter's 3 topics are not weighted equally: Propagation of EM Waves (4 questions, 50%), Communication System (2 questions, 25%), and Modulation (2 questions, 25%) have been asked the most. Over the last five years the most frequent topics have been Modulation (2).
