An electronic circuit that reduces a narrow range of frequencies. A notch filter is a type of bandstop filter. For example, in a musical instrument amplifier, a notch filter may reduce the ...

So we’ll look into an entirely different filter, the Twin-T notch filter, that turns out to be sharp enough to build a sine-wave oscillator on, and tweakable enough that we’ll make a damped ...

This report describes the theory of the "T"-type coaxial notch filter and presents design curves enabling the dimensions of practical filters to be calculated rapidly. The type of filter ...

Coming in the same brutish-looking form factor as the DS-2, this includes both an emulation of the smooth 2045 low-pass filter and Stylophone’s dirtier Gen R-8 filter, creating a device that the ...
