Q1:

For a bit rate of 8 kbps, the best possible values of the transmitted frequencies in a coherent binary FSK system are

A 16 kHz and 20 kHz

B 20 kHz and 32 kHz

C 20 kHz and 40 kHz

D 32 kHz and 40 kHz

ANS:D - 32 kHz and 40 kHz

where i is integer, and nc is fixed integer. fi = Rb(nc + i) (3 + 1) x 8 32 kHz (4 + 1)0.8 40 kHz.
