Re: IIT Kharagpur M Tech Interview Questions

Here I am providing the list of few Indian Institute of Technology Kharagpur M Tech Interview Questions which you are looking for .

• formula of DFT
• Sampling thm.
• peroidicity of DFT.
• Define LTV system, give examples
• spectrum of white noise.
• two systems were given, cascaded, transfer func in z domain, find net impulse response.
• Relation between i/p & o/p PSD.
• Nyquist rate in practical systems.
• draw voltage divider bias, why its called so, how u will increase bandwidth in dis ckt.
• range of visible light(frequency)
• Y(w) = exp(jw), interpret it.
• how does FFT reduces computational complexity.
• convolution formula nd does it apply to all kind of system, if not write convolution formula for LTV system (Answer is in oppenhiem & wilsky).
• waveform of bsk.
• a bit stream was given, draw qpsk
• how will u find B.W of a signal.
• Define probability. (dnt give formula of probability i.e fav. otcome divided by total, there are three definitions of probabilty, find in any standard book)
• Define Random variable.
• what are stochastic process.
• graph & laplace ofsome basic signals.
• What is need of VLSI.
