Question:
An FM transmitter without signal input is called:
An FM transmitter without signal input is called:
Show Hint
Frequency modulation involves changing the frequency of a carrier wave in response to an input signal, but without a signal, no modulation occurs.
Updated On: Jan 6, 2026
- Modulation
- Frequency deviation
- Frequency modulation
- None of the above
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding FM transmitter operation.
An FM transmitter without input is simply not transmitting a signal. The term "frequency modulation" refers to how the carrier frequency is varied according to the input signal.
Step 2: Conclusion. Thus, it is not correct to name the transmitter in this case as any of the listed options.
Step 2: Conclusion. Thus, it is not correct to name the transmitter in this case as any of the listed options.
