17. Section 11.6.1 states that when using 4B/5B encoding, a signal-carrying capacity of 125MHz is required for a transmission medium to have a bit rate of 100Mbps.
a) What signal-carrying capacity would be required if Manchester coding were used instead?
b) What signal-carrying capacity would be required if modified frequency modulation (MFM) coding were used, assuming that the occurrence of a 0 or a 1 are equally likely events?
(Manchester and MFM coding are explained in Chapter 2.)
