For a bit rate of 8 kbps, the best possible values of the transmitted frequencies in a coherent binary FSK system are
Answer: Option
Explanation:
where i is integer, and nc is fixed integer.
fi = Rb(nc + i)

Bandwidth for BPSK, B = bit rate = 8 kHz.
D is correct since 40kHz - 32KHz = 8kHz.
D is correct since 40kHz - 32KHz = 8kHz.

This answer is wrong.
Correct answer is option C.
BW of FSK => f1 - f2 + 2Rb
f1 - f2 must be greater than 2Rb in order to avoid distortion.
