The maximum data rate of that modem is doubled if the number of points in its constellation were doubled
According to statement
Modem has a data rate is 14,400 bps
we know that the data rate can be calculated by T=A/S
If a is Doubled then the data rate is also doubled.
Because A is directly proportional to the T and S is inversely proportional to T.
So, The maximum data rate of that modem is doubled if the number of points in its constellation were doubled
