What does stopband mean?
A stopband refers to a specific range of frequencies that are intentionally attenuated or blocked by a filter or signal processing system. This concept is crucial in various fields, including electrical engineering, telecommunications, and audio processing. The stopband is often defined in relation to a passband, which is the range of frequencies that are allowed to pass through with minimal attenuation. Understanding stopbands is essential for designing and optimizing filters and other signal processing systems. By carefully controlling the stopband, engineers can minimize interference, reduce noise, and improve overall system performance. The term stopband is primarily used in technical contexts and is an important concept in the design and analysis of signal processing systems.
nounA stopband is a range of frequencies that are rejected or attenuated by a filter or other signal processing system. It is the frequency range that is intentionally blocked or diminished.
- A range of frequencies rejected by a filter.
- A specific frequency range in signal processing.
"The audio filter was designed to have a stopband between 200-400 Hz to reduce background noise."
"The stopband of the filter was carefully calibrated to minimize interference."
"The engineer adjusted the stopband to optimize the system's performance."
The plural form is used when referring to multiple stopbands or frequency ranges.
"The system has multiple stopbands to attenuate different frequency ranges."

Etymology of stopband
The term stopband is derived from the words 'stop' and 'band', referring to a range of frequencies that are stopped or attenuated. The concept of stopbands emerged in the context of electrical engineering and signal processing, where filters are used to selectively allow or block specific frequency ranges.
How stopband is actually used
Typically used in technical contexts, such as electrical engineering or signal processing.
