Question

In FM, the noise can be further decreased by _________.
(a) Decreasing deviation
(b) Increasing deviation
(c) Keeping deviation constant
(d) None of these

Answer 1

Answer:

(b) increasing deviation

Answer 2

In FM, the noise can be further decreased by Increasing deviation.

Explanation:

• Frequency deviation in FM is defined as the way to describe the difference between the minimum and maximum extent of a frequency modulated signal and the carrier frequency.
• The amplitude of the modulating signal is converted to frequency variations of the FM ( Frequency Modulation ) signal. These variations are referred to as carrier deviation or deviation.

Hence,

Option (b) Increasing deviation is correct.
