** Subtractive synthesis, a method of creating a sound by removing harmonics, characterised by the application of an audio filter to an audio signal

** Pass band or Passband, the range of frequencies that can pass through an electronic filter without being attenuated

** SAW filter, a type of electronic filter

** In the case of narrow-band bandpass filters, the Q determines the-3dB bandwidth but also the degree of rejection of frequencies far removed from the center frequency ; if these two requirements are in conflict then a staggered-tuning bandpass filter may be needed.

** For high-pass and low-pass ( as well as band-pass filters far from the center frequency ), the required rejection may determine the slope of attenuation needed, and thus the " order " of the filter.

** Chebyshev filter – slight peaking / ripple in the passband before the corner ; Q > 0. 7071 for 2nd-order filters

** Butterworth filter – flattest amplitude response ; Q = 0. 7071 for 2nd-order filters
