Question
An AM signal is specified by$$f(t)=10(1+4 \cos 200 \pi t) \cos \pi \times 10^{4} t$$Determine the following:(a) the carrier frequency,(b) the lower sideband frequency,(c) the upper sideband frequency.
Step 1
Step 1: The given AM signal is $$f(t)=10(1+4 \cos 200 \pi t) \cos \pi \times 10^{4} t$$ This can be compared with the standard form of an AM signal $$f(t)=A_c(1+\mu \cos \omega_m t) \cos \omega_c t$$ where $A_c$ is the carrier amplitude, $\mu$ is the modulation Show more…

A signal $\mathrm{e}_{\mathrm{m}}=20 \sin 2000 \pi \mathrm{t}$ amplitude modulates a carries wave $e_{c}=80 \sin 200000 \pi t$. The percentage of modulation is (A) $25 \%$ (B) $0.25 \%$ (C) $400 \%$ (D) $40 \%$
A traveling wave is given in SI units by the expression $$\psi(y, t)=10 \sin 2 \pi\left(5.0 \times 10^{14}\right)\left(\frac{y}{3.0 \times 10^{8}}+t\right)$$ Find its (a) amplitude, (b) frequency, (c) wavelength,(d) speed, (e) period, and (f) direction of propagation.
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
