This Macro contains properties of analog and digital filters applied to waveform data. It can be used for filter settings applied on the recording device at the time of data acquisition as well as for filter settings used to achieve a specific waveform display.
Table C.10.12-1. Waveform Filter Characteristics Macro Attributes
Nominal 3dB point of lower frequency of pass band in Hz. This is the cutoff frequency of a high-pass filter. Required if the filter is a high-pass filter. Shall be consistent with Filter Low Frequency (003A,0220) in the enclosing Dataset, if present. |
|||
Nominal 3dB point of upper frequency of pass band in Hz. This is the cutoff frequency of a low-pass filter. Required if the filter is a low-pass filter. Shall be consistent with Filter High Frequency (003A,0221) in the enclosing Dataset, if present. |
|||
Characteristic parameters of the analog filter. |
|||
The slope of the filter response between pass-band and stop-band given in dB/octave. |

>>Include Table 8.8-1 “Code Sequence Macro Attributes” . |
|||
Characteristic parameters of the digital filter. |
|||
Filter order is the maximum delay, in samples, used in creating each output sample. |
