A 10 kHz sinusoidal is to be transmitted using FM in the presence of additive white Gaussian noise. The SNR improvement at the demodulator output is required to be 20 dB. Determine the peak frequency deviation required if

(a) No pre-emphasis/de-emphasis is used.
(b) A standard pre-emphasis/de-emphasis (with 1 f = 2.1 kHz ) is used.
(c) Based on your answers in parts (a) and (b), for a given output SNR, which FM system (with or without pre-emphasis/de-emphasis) will provide a larger baseband signal bandwidth?
