electrical noise
Unwanted signal disturbance
Electrical noise is unwanted disturbance in an electrical signal—random fluctuations that interfere with the intended information.
Sources include electromagnetic interference from nearby devices, thermal agitation in circuits, or power line hum.
Engineers work to minimize noise to improve signal clarity: The recording had too much electrical noise to be usable.
The concept extends to any system where interference degrades performance.
