HPF (High Pass Filter)
The HPF passes the signals above the specified cutoff
frequency set in the Freq parameter (below), and cuts
the signals below it.
Level
Cutoff
range
Cutoff frequency
Freq (Frequency)
Sets the cutoff frequency. This determines the cutoff
frequency of the filter, or the frequency below which
all other frequencies are filtered out.
Settings: 0~251
All other parameters for this filter are the same as
explained for the LPF (Low Pass Filter) parameters.
For information, see page 88.
BPF (Band Pass Filter)
The BPF filter passes only a band of frequencies
centered at the cutoff frequency, and cuts others.

Freq (Frequency)
Sets the cutoff frequency. Only the frequencies
around the cutoff frequency will be passed, while
other frequencies will be filtered out.

All other parameters for this filter are the same as
explained for the LPF parameters. For information,
see page 88.
InvertLPF (Inverted Low Pass Filter)
The InvLPF inverts the function of the LPF. The
signals below the specified cutoff frequency are filtered
out, and other frequencies are passed. The InvLPF and
LPF form a symmetrical curve on the horizontal axis.
Level
Cutoff range
Freq (Frequency)
Sets the cutoff frequency. The frequencies below the
cutoff frequency are filtered out.
Settings: 0~229
All other parameters for this filter are the same as
explained for the LPF parameters. For information,
