A 500 Hz modulating voltage fed into an FM generator produces a frequency deviation of 2.25 kHz. If amplitude of the voltage is kept constant but frequency is raised to 6 kHz then the new deviation will be (a) 4.5 kHz (b) 54 kHz (c) 27 kHz (d) 15 kHz

Step 1
25 kHz, modulating frequency (FM) = 500 Hz Modulation index (μ) = Δ / FM Convert kHz to Hz: 2.25 kHz = 2250 Hz μ = 2250 / 500 = 4.5 ** Show more…

The modulation index of a FM signal is $0.25$. If modulating frequency is $2 \mathrm{kHz}$, the maximum deviation in frequency would be (a) $500 \mathrm{~Hz}$ (b) $1000 \mathrm{~Hz}$ (c) $1500 \mathrm{~Hz}$ (d) $500 \mathrm{kHz}$

Sinusoidal carrier voltage of frequency $1.5 \mathrm{MHz}$ and amplitude $50 \mathrm{~V}$ is amplitude modulated by sinusoidal voltage of frequency $10 \mathrm{kHz}$ producing $50 \%$ modulation. The lower and upper side band frequencies in $\mathrm{kHz}$ are (a) 1510,1490 (b) 1820,1012 (c) $\frac{1}{1510}, \frac{1}{1490}$ (d) 2490,1510
