What is the total bandwidth of an FM phone transmission having 5 kHz deviation and 3 kHz modulating frequency?
Pick an answer to check it.
Answer: D. 16 kHz
Use Carson's rule: bandwidth = 2 x (deviation + modulating frequency) = 2 x (5 kHz + 3 kHz) = 16 kHz.
Tip: Carson's rule: 2 x (deviation + audio).
