Sorry, no etymologies found.
The full design comes from Thomas Pynchon's 'V.' -- it's a band-stop filter, used to eliminate noise in public address systems, amplifiers & the like.
Users can design multiple feedback (MFB), Sallen-Key, low-pass, high-pass, band-pass and band-stop filters using voltage feedback op amps.
If there is only one high power transmitter that you are worried about, then you could also use a tunable band-stop filter to remove that one signal.
