this examination and that I have reported all such incidents observed by me in which unpermitted aid is given.” Signature Name Student ID Question 1: [4 points] Consider a linear time-invariant (LTI) system with impulse response h(t) whose Fourier transform is H(f ) = ∧(f ). Recall that ∧(f ) is non-zero only from f = −1 to f = +1. Find the output of the system if the input is: (a) x(t) = sin 0.5πt Solution: ∧(0.25) sin 0.5πt = 0.75 sin 0.5πt (b) x(t) = cos 10πt Solution: ∧(5) cos 10πt = 0 Question

being multiplication. • Real Time Systems demand instantaneous response to environmental variables and quick execution of taken decision. • Multiplication algorithms find applications in Digital Signal Processing (DSP) for discrete Fourier transforms‚ Fast Fourier transforms‚ convolution‚ digital filters‚ etc. Therefore any new multiplication algorithm opens up a new approach for improving existing schemes. This calls for a ‘time efficient’ algorithm for ‘multiplication’ to improve processor throughput

ANSWERS BRIEF AND TO THE POINT. DON’T WASTE TIME WRITING LONG DISCUSSIONS. SOME Useful Facts • xn = f0 G(nf0 )‚ where xn are the Fourier Series coefficients of periodic signal x(t)‚ and G(f ) is the Fourier Transform of a single period of x(t). • “Convolution of a signal of width w1 with a signal of width w2 results in a signal of width w1 + w2 .” • From the Fourier Transform table: k=∞ n=∞ w(t) = k=−∞ δ(t − kT ) ⇐⇒ W (f ) = 1/T n=−∞ δ(f − n/T ) 2 1. 10% dB problem: The output signal
