4.6.2. Consider a modified form of partial-response signaling where, instead of the relationship
w(t) = x(t)+x(t−Ts), the corresponding relationship is w(t) = x(t+Ts)+x(t)−2x(t−Ts).
(a) Determine hG(t).
(b) Determine HG(f).
(c) Determine hG(kTs) for k = −3, −2, −1, 0, 1, 2, and 3. Also determine HG(0) and
determine the absolute bandwidth of HG(f).
