Vedclass · Answer

(D) In amplitude modulation, the carrier frequency $(f_c)$ must be significantly higher than the modulating (audio) frequency $(f_m)$ to ensure efficient transmission and signal processing.Typically, the carrier frequency is chosen to be at least $100$ times the modulating frequency.Given $f_m = 500 \, 	ext{Hz}$.Among the given options, $50,000 \, 	ext{Hz}$ $(50 \, 	ext{kHz})$ is the only value that satisfies the condition $f_c \gg f_m$.Therefore, the correct carrier frequency is $50,000 \, 	ext{cycles/sec}$.

For an amplitude-modulated wave, the audio frequency is $500 \, \text{cycles/second}$. What is the actual carrier frequency in $\text{cycles/sec}$?
