Explain the terms (i) Attenuation and (ii) Demodulation used in Communication System.
Given,
Charge (q) is the same but the mass of both particles is different (m1 > m2).
The De-broglie wavelength given by,
The slope of the graph of λ versus =
The slope of the smaller mass is larger; therefore, plat A in the above graph represents mass m2.
(a) Explain any two factors that justify the need of modulating a low-frequency signal.
(b) Write two advantages of frequency modulation over amplitude modulation.
