Question

In an amplitude modulated wave for audio-frequency of $500$ cycles/second, the appropriate carrier frequency can be

• A. $50\text{cycles/sec}$.
• B. $100\text{cycles/sec}$.
• C. $500\text{cycles/sec}$
• D. $50,000\text{cycles /sec}$

Answer 1

The correct option is D $50,000\text{cycles /sec}$

Carrier frequency $F_C$> audio frequency
$F_C>500$
option D
