A
Notch Filter
is just the opposite of a bandpass filter and is used to eliminate a
narrow band of frequencies.
Another control found on traditional filters is called Q or resonance. A lowpass
filter with a high Q would emphasize the frequencies around the cutoff fre-
quency. The chart below shows how different amounts of Q affect the low pass
filter response. In terms of sound, frequencies around the cutoff will tend to
“ring” with high Q settings. If the filter is slowly swept back and forth, with a
high Q, various overtones will be “picked out” of the sound and amplified as the
resonant peak sweeps over them. Bells and gongs are real world examples of
sounds which have a high Q.
Another characteristic of a filter is the number of poles it contains. Traditional
synthesizer filters were usually either 2-pole or 4-pole filters. The number of
poles in a filter describes the steepness of its slope. The more poles, the steeper
the filter's slope and the stronger the filtering action. The tone controls on your
home stereo are probably one-pole or two-pole filters. Parametric equalizers are
usually either two-pole or three-pole filters. In terms of vintage synthesizers,
Moog and ARP synthesizer filters used 4-pole filters, Oberheim synthesizers
were famous for their 2-pole filter sound.
