A signal from a transducer is a function of time (t): x(t) = sin(2л*350t) + 1.8cos(2л*300t) + 2sin(2л*kt)*cos(2л*250t) where k is unknown. The power spectrum of the signal after Fourier transform is shown below. Derive the value of k. Power I 0 50 100 150 200 250 300 350 400 Frequency (Hz) (Tip: sina*cosb = 0.5[sin(a+b)+sin(a-b)]) A signal from a transducer is a function of time (t): x(t) = sin(2л*350t) + 1.8cos(2л*300t) + 2sin(2л*kt)*cos(2л*250t) where k is unknown.
