noise is an unwanted signal. not all noise is considered as distortion but sometimes it is.

Noise would typically be additive to original signal. Distortion would probably represent a chance to an original signal. So in general, we expect noise would be uncorrelated to original signal, distortion error would be highly -correlated to the original signal.

in general.noise is an external source that change the normal shape of signal and distortion is the difference of normal shape and shape that u obtain .

Hi

Noise is external signal which affects your signal, it's not correlated to your signal

While distortions is deformation of your signal.
distortion may be due to power supply limitations , non linearity ,band limited filters

Thanks replying, well what I am able to understand is that the noise is an unwanted signal that is added to your original signal and distortions is an unwanted signal that is added to your signal nonlinearly. Correct me if am wrong
