Question: 17. Section 12.6.1 states that when using 4B/5B encoding, a signal-carrying capacity of 125MHz is required for a transmission medium to have a bit rate

17. Section 12.6.1 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 and the occurance of a 1 are equally likely events?

(Manchester and MFM coding are explained in Chapter 2, Section 2.A.)
