Explanation:

Answer 2

Answer:

A standard FM signal is represented by

v(t)=AcCos(2πfct+Kfsin2πfmt)

Ac=carrier amplitude

fc=carrier frequency

Kf=modulation index

fm=modulating frequency=2200/2π=350Hz

Kf=frequency deviation/modulating frequency

S=frequency deviation/350

therefore, deviation=5×350

=1750Hz
