For the signal 2a g(1) = determine the essential bandwidth B Hz of g(t) such that the energy contained in the spectral components of g(t) of frequencies below B Hz is 99% of the signal energy Eg. Hint: Determine G(f) by applying the duality property [Eq (3.26)] to pair 3 of Table 3.1. TABLE 3.1 SOME COMMON 2-TRANSFORM PAIRS Transform ROC Sequence 1. All: 1 2. u[r] 3. -u[-n - 1] 4.
