Vestigial sideband modulation (VSB), discussed in Chapter, offers another modulation method for pass b and data transmission.

(a) In particular, a digital VSB transmission system may be viewed as a time-varying one- dimensional system operating at a rate of 2fF dimensions per second, where T is the symbol period. Justify the validity of this statement.

(b) Show that digital VSB is indeed equivalent in performance to the offset QPSK.
