Answer / pozhilan.s

noise are unwanted signal signal is mixed in fundamental
signal. distortion are fundamental signal affected due to
external disturbance.

Answer / siva subrahmanyam

Noise may bge defned as the external signal which is
unwanted to the original communication, it may be of any
type.
Where as distortion is a problem associated with basic
message signal because of the addition of the noise. That
problem may be variations in the amplitude, phase or
frequency etc...

Answer / chhina

Noise: it is a unwanted signal . THUS THESE UNWANTED
SIGNAL IS REFFERED AS NOISE. WHICH DEGRADE THE THE QUALITY
OF THE SIGNAL.
Distortion; WHEN TWO OR MORE SIGNALS CONTRACT WITH EACH
OTHER(DUE TO IMPROPER LAUNCHING,THEN RECEIVED SIGNAL IS
REFFERED AS A DISTORTED SIGNAL. WHICH LIMITS THE POWER OF
THE SIGNAL.

Answer / ifraz inam khan

Noise defined as the unwanted modulation or unwanted signal that gets superimposed with the information signal

Distortion defined as any unexpected change in the shape of any waveform.In this case signal is no longer pure but it has additional frequency components which are known as harmonics.

Answer / bhushan

NOISE IS THE UNWANTED RANDOM SIGNAL.
DISTORTION IS EFFECT DUE TO HARMONICS OF THE SIGNAL

Answer / anil

distortion is caused by the non linearty of the devices
present in the circuit......noise is due to hum in the
power lines ....

Answer / srinu

noise is due to the external disturbance
where as the distortions due to the internal disturbance of
the ciruit or system

Answer / sai deshmukh

distortion produce by noise ,noise does not produce by noise
