A FM Broad cast transmitter, using modulating signal of frequency has a deviation ratio of 10. The Bandwidth required for transmission is
View answer and explanation
Correct option: D
440 kHz
Option D (440 kHz) is correct because the bandwidth is calculated using Carson's rule: BW = 2(Δf + fm), where Δf is the frequency deviation and fm is the modulating signal frequency.
