(a) A 60Hz cosine signal is sampled using a sampling frequency of 500Hz. 64 samples are acquired and stored in x[n]. A 64 point FFT of x[n] forms X[k], k=0,1,2...63. Determine which spectral coefficients will have the largest magnitudes. (b) Find the sampling frequency closest to 500Hz that will eliminate spectral leakage from part (a) above. (c) Estimate the Scallop Loss for a Hann window of length 4. The formulae for the Hann window can be found in the formulae sheets and you may use the radix-2 Decimation-in- time FFT, the DFT, the DTFT or any other analytic method in this problem (d) Write concise notes on the fundamentals of compressive sensing in signal processing. Use appropriate illustrations in your answer.
