External noise cannot be reduced except by changing the location of the receiver or the entire system. Owen Bishop, in Understand Electronics (Second Edition), 2001. Get a high-level overview of the sources and impact of noise in electronic amplifiers. External noise is a disruption in the communication that occurs outside of the mind of the receiver . This can occur between the sender to the medium, or from the medium to the receiver. Internal noise is inside the mind of the receiver that does not allow the message to be received perfectly. When external noise occurs, the message will be disturbed when it is being sent from the sender to the receiver. • Electronic shot noise is the consequence of random fluctuations in electrical current when electrons or other charge carriers move across a barrier.
