is further reduced. Generally, dynamic restrictions are due to noisy storage in transmission media and also the
maximum headroom of these systems.
4.3.1 Noise as a physical phenomenon
All electrical components produce a certain level of inherent noise. Current flowing through a conductor leads
to uncontrolled random electron movements. For statistical reasons, this produces frequencies within the
whole audio spectrum. If these currents are highly amplified, the result will be perceived as noise. Since all
frequencies are equally affected, we term this white noise. It is fairly obvious that electronics cannot function
without components. Even if special low-noise components are used, a certain degree of basic noise cannot
be avoided.
