Filter Type (Filter Type)
The following digital filter types are available: Gauss, Sharp, IIR, and Mean. The features of each filter are listed
below.
Filter Type Features Operation Type
Gauss • Frequency characteristics with a smooth attenuation slope FIR
• Linear phase and constant group delay
• No ripples present in the passband
• No overshoot in the step response
•
Low order and short delay
Sharp • Frequency characteristics with a sharp attenuation slope
(−40 dB at 1 oct)
FIR
• Linear phase and constant group delay
• Ripples present in the passband
•
Comb-shaped stopband
IIR • Attenuation slope steepness between those of the SHARP and
GAUSS filters
IIR
• Non-linear phase and non-constant group delay
• No ripples present in the passband and stopband
•
Characteristics similar to those of analog filters
• Compared to Sharp and Gauss filters, lower cutoff frequency
possible
Mean •
Comb-shaped frequency characteristics FIR
• Linear phase and constant group delay
• No overshoot in the step response
IIR-LowPass • Computes at 10 MS/s regardless of the setting. IIR
Filter Band (Filter Band)
When the filter type is set to Gauss, Sharp, or IIR, you can select the filter band. The type of filter band that you
can select depends on the filter type.
Filter Type Filter Band
Gauss Low-Pass
Sharp Low-Pass, High-Pass, Band-Pass
IIR Low-Pass, High-Pass, Band-Pass
Cutoff Frequency (CutOff)
When the filter type is set to Sharp, Gauss, or IIR and the filter band is set to Low-Pass or High-Pass, you can
set the cutoff frequency. The ranges and resolutions are indicated below.
