stopband
stopband
Noun
pl: stopbands
This term is a technical specification used primarily in electrical engineering and signal processing. It describes the specific frequency region where a filter prevents signals from passing, contrasting directly with the passband, where signals are allowed to flow.
In professional contexts, the term is used to define the performance limits of a circuit. Engineers often discuss the steepness of the transition between the passband and the stopband to describe how efficiently a filter can isolate unwanted noise from a desired signal.
Meanings
Nounstopband
A range of frequencies in a filter or electronic circuit that are significantly attenuated or blocked from passing through.
The filter was designed with a wide stopband to eliminate high-frequency noise.
