Noise is a limiting factor is many receivers and other systems. Essentially, it is unwanted energy that sets the sensitivity of a receiver. Noise masks signals of interest at lower levels, preventing the receiver from detecting them. It is almost unavoidable and exists in all electronic systems, from audio and baseband electronic devices through the highest terahertz frequencies and optical electronic systems. While it cannot be eliminated, it can be controlled and managed, enabling receivers
