A message signal m(t) = Am sin (2πfmt) is used to modulate the phase of a carrier Ac cos (2πfct) to get the modulated signal y(t) = Ac cos (2πfct + m(t)). The bandwidth of y(t)

A message signal m(t) = Am sin (2πfmt) is used to modulate the phase

1.	A message signal m(t) = Am sin (2πfmt) is used to modulate the phase of a carrier Ac cos (2πfct) to get the modulated signal y(t) = Ac cos (2πfct + m(t)). The bandwidth of y(t)
A.	depends on Am but not on fm
B.	depends on fm but not on Am
C.	depends on both Am and fm
D.	does not depends on Am or fm
Answer» D. does not depends on Am or fm
