what is angle and amplitude modulation? what is noise in
modulation?
Answers were Sorted based on User's Feedback
angle modulation :it is the process of varying angle of a
signal ( carrier signal) with respect to instaneous
amplitude of another signal known as message signal.
***
angle in the sense either frequency or phase.
amplitude modulation :it is the process of varying
amplitude of a signal ( carrier signal which is with zero
reference ) with respect to instaneous amplitude of another
signal known as message signal
noise :
unnecessary things occured in the process of modulation
that may be either amplitude or frequency or phase.

Answer / srikrishna
The answer above is completely in correct.,sorry to tell
this.
ANGLE MODULATION means
the angle (here angle means the phase of the signal or
frequency of the signal),of the carrier signal is varied in
accordance with the message signal.
here we dont change the charicteristic of the message
signal we have to change one of the charecterisic of the
carrier signal.
Amplitude modulation means the carrier amolitude is to be
varied with respect tothe message signal.
Noise means the unwanted signal frequencywhich is probed
into the actual required signal and effects the
charecteristics of the original signal.
noise is a wide band signal i.e. it will present at all
frequencies but at some frequencies the effect of noise may
be low.

Answer / d.dinesh
Angle Modulation:
Varying the frequency of the modulating signal
(message signal) with respect to carrier signal to
get a angle modulated signal
Amplitude Modulation:
Varying the amplitude of the message signal with
respect to carrier signal to get amplituted
modulated signal
Noise:
Noise is unwanted disturbances in a signal
