An electronic filter that blocks or attenuates signals within a specific frequency range while allowing frequencies outside that range to pass through.
Compound of band and stop, created in the 20th century as electronics developed. It's the opposite of a bandpass filter.
Bandstop filters are like noise-canceling in reverse—instead of isolating what you want to hear, they surgically remove just the frequencies you don't want, which is why your home WiFi can block interference from microwave ovens.
