Question

In amplitude modulation -; 1) Amplitude of the carrier is kept constant; 2) Change occurs in carrier frequency; 3) Amplitude is varied according to the instaneous value of modelling wave; 4) None of these

Answer 1

❀ $\large{ \underline\textbf{Answer - }}$

In amplitude modulation :-
1) Amplitude of the carrier is kept constant

2) Change occurs in carrier frequency

3) Amplitude is varied according to the instaneous value of modelling wave✔️✔️✔️

4) None of these


In amplitude modulation ${ \underline{\textbf{Amplitude is varied according to the instaneous value of modelling wave}}}$.

Answer 2

$\mathfrak{The\:Answer\:is}$
