Time-limited signals cannot be bandlimited, but their rate of decay in the fre-
quency domain depends on the sharpness of the transitions in the time domain. For each of the
time-limited signals below, estimate the rate of decay of |Â(ƒ)| as |ƒ| gets large. You should be
able to answer this without detailed computation of the Fourier transform.
(a) x₁(t) = (2
(b) x₂(t) = |t|I-2,2] (t).
(c) 23(t) = cos(πt/4)I-2,2] (t).
