| * Phase Equalization: If you would like to have the FIR filter do phase equalization, you can turn on the "Phase Equalization" option, as shown in the figure below. The main purpose of the phase equalization is to reduce the pass band group delay *variance*, so that for signals at different frequencies, they will be delayed by an almost identical amount when going through the filter chain. | * Phase Equalization: If you would like to have the FIR filter do phase equalization, you can turn on the "Phase Equalization" option, as shown in the figure below. The main purpose of the phase equalization is to reduce the pass band group delay *variance* brought by analog filters, digital filters and FIR filter, so that for signals at different frequencies, they will be delayed by an almost identical amount when going through the filter chain. |
