One major problem in real instrumentation systems is electromagnetic interference caused by the 60 Hz power lines. A system with h(t)=A[u(t) - u(t-t0)] can reject 60 Hz and all its harmonics. Find the numerical value of to that makes this happen. A. t0=1/240 B. t0=1/120 C. t0=1/60 D. t0=1/30 E. None of the above Which of the following is FALSE for the Fourier spectrum? A. The magnitude of the spectrum at f=fa indicates how much of fa is present in the signal. B. If x(t) is even, the Fourier spectrum is pure imaginary. C. The phase of the spectrum is a measure of the time offset or delay of a specific frequency component. D.
