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.
