signal-to-noise ratio

• Technischer Begriff aus der Elektronik und Telekommunikation, der das Verhältnis der Stärke eines Nutzsignals zum Hintergrundrauschen bezeichnet. Im weiteren Sinne metaphorisch verwendet für das Verhältnis von relevanter oder nützlicher Information zu irrelevanten oder ablenkenden Inhalten.

A technical term originally from electronics and telecommunications, referring to the level of a desired signal compared to the level of background noise. In broader contexts, it is used metaphorically to describe the amount of useful or relevant information compared to irrelevant or distracting content.

1. Technical measurementC1formal

   A measure used in science and engineering that compares the level of a desired signal to the level of background noise.
