Vedclass · Answer

(D) In amplitude modulation, the carrier frequency $(f_c)$ must be significantly higher than the modulating signal frequency $(f_m)$ to ensure efficient transmission and to avoid overlapping of sidebands.Typically, $f_c \gg f_m$.Given the audio frequency $f_m = 500 \, 	ext{Hz}$.Among the given options, $50000 \, 	ext{Hz}$ is the only value that is significantly greater than $500 \, 	ext{Hz}$.Therefore, the appropriate carrier frequency is $50000 \, 	ext{cycles/second}$.

In an amplitude modulated wave for an audio frequency of $500 \, \text{cycles/second}$, the appropriate carrier frequency will be ........ $\text{cycles/second}$.
