The channel capacity of a telephone line noisy channel is 110 kbps with bandwidth (B=3 kHz). Find the following: • The new value of the channel capacity if the cable is replaced by a coaxial cable with bandwidth (B=500kHz). Assume no changes of both transmitted power and channel noise. • The new value of S/N ratio in the telephone line (B=3 kHz) to increase the value of channel capacity to be equal to that of the coaxial cable.
