A more accurate description of real signals is given by A(t)sin([phi](t)), where A(t) is a fluctuating amplitude with AM noise and [phi](t) describes phase fluctuation noise with an average derivative that is called the center frequency.
The signals arriving from different sensors are subjected to the influence of various noises and distortions (fluctuation noises, optical distortions, distortions caused by sensors, etc.).
