Unformatted text preview: (iii) Estimate of R1/R2 equals ((a1^2 + b1^2)/(a2^2 + b2^2))^(-gamma) = 0.8349 (iv) S = fft(s) plot(abs(S)), title('Plot of abs(fft(s))') % see hw17graph2.pdf The ratio of the two peaks is given by 450.7/411.6 = 1.0951 Note that the quantity (a1^2 + b1^2)/(a2^2 + b2^2))^(1/2) which estimates the ratio of the two amplitudes in the expression for s(t), equals 1.06. (The taller peak corresponds to f1 = 3 MHz, the shorter peak to f2 = 2.5 MHz.) Sheet1 Page 3...
