What causes noise in signal processing?

The causes of noise can be from the circuit itself, an imperfect design or layout, noise generated by faulty components or loose connections, or switches in related circuits or in switching power supplies that feed the circuit. Even long leads can cause induced noise.

What can happen if there is too much noise in a digital signal?

Though uncommon, extreme signal noise can lead to an apparent loss of signal. Most modern electronic equipment have built in noise filtering. However, in extremely noisy environments, this filter will not be enough, which can lead to the equipment not receiving a signal and no communication taking place at all.

What is noise in digital signal processing?

Noise can be defined as an unwanted signal that interferes with the communication or measurement of another signal.
