The maximum deviation allowed in an FM broadcast system is 75 kHz. If the modulating signal is a single-tone sinusoid of 10 kHz, then the bandwidth of the FM signal—
-
- 170 kHz
- 190 kHz
- 150 kHz
- None of these
- 170 kHz
Correct Option: A
Given, Δf = 75 kHz
fm = 10 kHz
The BW is given by,
BW = 2(Δf + fm)
= 2 × 75 kHz + 2 × 10 kHz
= 170 kHz
