Find the desired bandwidths of the signals whose power spectrum are given below with the MATLAB; Briefly explain the path you followed while finding the bandwidth. 1) Noise equivalent bandwidth. G1(f) 1 -f2 - fi 0 fi f2 f ii) null-to-null bandwidth. For this question, plot the Gz(f) on the logarithmic axis using MATLAB and show the bandwidth 1 G(f)=17 1+ 10-8 cos? (5 arccos() 3)) iii) 99% bandwidth. G3(f) 1 -f3 0 f3 f
