Re: Anna University Chennai DSP Question Paper
Here I am providing the list of few questions of DSP Question Paper of Anna University Chennai which you are looking for . State and prove the convolution property of Z transform. Check the system is linear or not y(n) = x(n)+ay(n1) Write equations for finding DFT and IDFT using Z transform. Draw the radix 2 butterfly structure for DIF Draw the implementation for the generalized for IIR filter using direct form II. Explain how the addition and multiplication of (H1, H2) impulse responses implemented in filter design Write equations for Hanning and Blackman window. Why frequency prewarping procedure is adopted in the design of IIR filter? Write two advantages of musical sound processing and briefly explain. Explain the effects due to upsampling.
