Relationship between transmission rates bandwith $$ = f_B $$
Binary data rate $$ = R_s = \frac{1}{T_s} $$
Roll off factor $$ f_B = \frac{1+\alpha}{2*T_s} $$
trade-off: An increase in a increase the required bandwidth but decrease the ISI, and vice versa.
Sample signal and ideal low-pass filter $$ Example: \newline m(t) = 6cos(8,000\pi t) + 2cos(20,000\pi t) $$

Sample rate $$ = f_s > 2 * Highest \space Frequency \space component $$
