A signal from a transducer is a function of time (t): 2 (t) = 5 sin(27 x 350t) + 7 cos(2 x 300t) + 10 sin(27 kt) cos(26 x 250t) where k is unknown. The power spectrum of the signal after Fourier transform is shown below. Derive the value of k. Power 0 50 100 150 200 250 300 350 400 Frequency (Hz) (Hint: sin a cos B = (sin(a +B) + sin(a – B)]) =
