SECTION A Quiz-1. Fourier series has many applications in electrical engineering, telecommunica acoustics, opties, signal processing, image processing, and quantum signals into the sum of sines and cosines. However, Fourier series analysis tions, vibration ana ete. It decomposes functios mechanics, A. Is only applicable to square waves B. Can only be employed to compute common mode rejectiorn C. Is used to determine the coefficients of fundamental signals (i.e. Sin and Cos signals) D. A and C both Quiz-2: The term bandwidth has a number of technical meanings but since the popularization of the internet, generally referred to the volume of information per unit of time that a transmission medium (like an in connection) can handle. In Communication theory, what is Null to Null bandwidth? A. Net Liniversal Line to Line bandwidth interval between first two nulls. C. Time period between any two nulls The band width that does not exist (i.e. Null) because of zero amplitude of DC components D. Quiz-3 Fourier series that is defined by themathematical expression x()24+4"0snar+4n nat A. B. C. Is known D. Is also known as exponential representation of Sine functions Is also known as Quadrature representation of Fourier Series as Polar representation of Phase Modulation Is known as First Stage of Fourier Series in Sin and Cos Domain. Quiz-4: Any Telecommunications Network is considered to be composed of A. At least 3 KEY blocks (i.e. Transmitter, Channel, and Receiver) B. Digital Multiplexing at Tx side, and Analog Multiplexing on Rx side C. Three fundamental components (Frequency, Wavelength, and Time Period) D. Both A and B Quiz-5: In any cellular system, it is necessary to have a scheme that enables several multiple users to gain acc the radio resource and use it simultaneously. They form the very core of the way in which the radio technology cellular system works. As cellular technology has progressed, multiple Radio Access Interfaces (RAls) have used. RAls historically used, or still in use in different Wireless Networks are: A. GPS, GPRS, EDGE, LTE B. MAT, PDG,MME, FDD C. FDMA, TDMA, CDMA, OFDMA D. None of above is correct Quiz-6: Rayleigh's energy theorem states that: A. The energy of a signal may be written in frequency domain as superposition of energies due to indi B. C. D. spectral frequencies of the signal The energy in a signal is not reliable The energy of a signal is negligibly small and can be ignored None of above Quiz-7: The sine function, also called the "sampling function," is a function that arises frequently in processing and the theory of Fourier transforms. The full name of the function is "sine cardinal," but it is com referred to by its abbreviation, "sinc. function". Pick the most accurate statement about the sinc function, f following four options PagExplanation / Answer
Q1 : Fourier series is genrally used to for representing any periodic functon as infinte sum of sines and cosines.This generally done to break the function into simple function which can be solved and then recombined to get original solution and also to know the harmonic content of given signal.It is applicable to any periodic function (not just square wave)
so, Option (C) is corrrect.
