Calculate the value of the signal rate for each case in Figure 4.2 if the data rate is 1 Mbps and c = 1/2.

Figure 4.2

a. One data element per one signal  element (r = 1)

b. One data element per two signal elements r = (1/2)

c. Two data elements per one signal  element (r = 2)

d. Four data elements per three signal  elements r = (4/3)
