LP2
Two-pole low-pass, frequencies above the
cutoff are attenuated at 12 dB/oct.
LP1
One-pole low-pass, frequencies above the
cutoff are attenuated at 6 dB/oct.
BP2
Two-pole band-pass, 6 dB/oct high-pass
and 6 dB/oct low-pass in series. Frequencies be-
low and above the cutoff are attenuated at
6 dB/oct.
BP4
Four-pole band-pass, 12 dB/oct high-pass
and 12 dB/oct low-pass in series. Frequencies be-
low and above the cutoff are attenuated at
12 dB/oct.
HP2+LP1
Combination that forms a three-pole
asymmetric band-pass. Frequencies below and
above the cutoff are attenuated. With a
12 dB/oct high-pass and a 6 dB/oct low-pass in
series, low frequencies are faster attenuated than
high frequencies.
HP3+LP1
Combination that forms a four-pole
asymmetric band-pass. Frequencies below and
above the cutoff are attenuated. With an
18 dB/oct high-pass and a 6 dB/oct low-pass in
series, low frequencies are faster attenuated than
high frequencies.
HP4
Four-pole high-pass, frequencies below the
cutoff are attenuated at 24 dB/oct.
HP3
Three-pole high-pass, frequencies below
the cutoff are attenuated at 18 dB/oct.
HP2
Two-pole high-pass, frequencies below the
cutoff are attenuated at 12 dB/oct.
HP1
One-pole high-pass, frequencies below the
cutoff are attenuated at 6 dB/oct.
BR2
Two-pole band reject, 6 dB/oct low-pass
and 6 dB/oct high-pass in parallel. Frequencies
around the cutoff are attenuated at 6 dB/oct.
BR4
Four-pole band reject, 12 dB/oct low-pass
and 12 dB/oct high-pass in parallel. Frequencies
around the cutoff are attenuated at 12 dB/oct.
BR2+LP1
Combination that forms a three-pole
asymmetric band reject. Frequencies around
and above the cutoff are attenuated. With a two-
pole band reject and a 6 dB/oct low-pass in
series, high frequencies obtain more attenuation
than mid frequencies.
BR2+LP2
Combination that forms a four-pole
asymmetric band reject. Frequencies around
and above the cutoff are attenuated. With a two-
pole band reject and a 12 dB/oct low-pass in
series, high frequencies obtain more attenuation
than mid frequencies.
HP1+BR2
Combination that forms a three-pole
asymmetric band reject. Frequencies below and
around the cutoff are attenuated. With a
6 dB/oct high-pass and a two-pole band reject in
series, low frequencies obtain more attenuation
than mid frequencies.
BP2+BR2
Combination that is sometimes called
a four-pole
tooth filter
because the frequency plot
of the filter forms the shape of a tooth. Frequen-
cies below, around, and above the cutoff are at-
tenuated.
HP1+LP2
Combination that forms a three-pole
asymmetric band-pass. Frequencies below and
above the cutoff are attenuated. With a 6 dB/oct
high-pass and a 12 dB/oct low-pass in series,
high frequencies are faster attenuated than low
frequencies.
HP1+LP3
Filter that forms a four-pole asymmet-
ric band-pass. Frequencies below and above the
cutoff are attenuated. With a 6 dB/oct high-pass
and an 18 dB/oct low-pass in series, high fre-
quencies are faster attenuated than low frequen-
cies.
