, Unwanted Signals which degrade the
desired signal content and thus the
performance of the system.
Types:-
External Noise- atmospheric interference,
man made interference, lightning
Internal Noise- Generated by the
components and devices used in the
system.
, Thermal noise
Shot noise
Micro phonic noise
Parasitic oscillations
Hum
, Most significant internal noise in
amplifiers.
Noise generated in resistance or resistive
component.
Produced by the random motion of
electrons in resistors.
