bandpass
|band-pass|
/ˈbændˌpæs/
allow a specific frequency range to pass
Etymology
'bandpass' originates from Modern English as a compound of 'band' + 'pass', where 'band' referred to a range (a strip or band) and 'pass' meant to allow to go through.
'bandpass' is a 20th-century technical compound formed in English (often written 'band-pass' in early usage) in the context of radio and electronic filter design; it emerged from phrases like 'pass band' and 'band-pass filter.'
Initially formed to name the concept of a 'pass band' (the part of the spectrum that passes through); it has remained focused on the idea of allowing a specific frequency band to pass while rejecting others.
