In electronics, noise is an unwanted disturbance in an electrical signal. [1] : 5. Noise generated by electronic devices varies greatly as it is produced by several different effects. In particular, noise is inherent in physics and central to thermodynamics. Any conductor with electrical resistance will generate thermal noise inherently.
21 de jun. de 2018 · Noise can “come from” anywhere: the air, the power supply, an LDO, a switching regulator, a resistor.... We want to go deeper, i.e., to the origins of the noise itself, rather than to the components or pathways by which noise enters a circuit. Thermal Noise, AKA Johnson Noise.

In the electronic sense, noise is an unwanted signal that is superimposed on a wanted signal. Much of a designer’s effort goes toward reducing it. Electronic noise may become apparent as actual noise, in the more usual sense, when we hear a crackling, humming, or hissing sounds in the background when listening to the radio.

12 de nov. de 2019 · Noise is an unwanted disturbance that degrades the accuracy of our desired signal. To analyze the effect of noise on a system, we need to have a basic understanding of its behavior.
Electrical noise is a collection of spontaneous fluctuations in currents and voltages. They are present in any electronic system and arise from thermal motion of the electrons and from the quantized nature of electric charge.
Electrical noise occurs when electrical signals produce undesirable effects in the electronic circuits of the control system. The term “electrical noise” originated with AM radios when the extraneous “noise” heard in the speaker was caused by lightning or other sources of electrical arcing.
