Q20.A FM Broad cast transmitter, using modulating signal of frequency 20 kHz has a deviation ratio of 10 . The Bandwidth required for transmission is : (1) 220 kHz (2) 180 kHz (3) 360 kHz (4) 440 kHz
What This Question Tests
This question tests the understanding of FM bandwidth using Carson's Rule, requiring the calculation of frequency deviation from the given deviation ratio and modulating frequency.
Concepts Tested
Formulas Used
Deviation Ratio (m_f) = Δf / f_m
Bandwidth (BW) = 2(Δf + f_m)
