Dew.Signal.TFractionalImpulse Enumeration
Structs, Records, Enums
Collapse All

Set of predefined FIR allpass filters suitable for fractional delay filtering. Filter specifications have been relaxed to allow variation of the amplitude in the stop band between 0 and 1 linear scale, but keeping the ripple specification in the passband. When unclear what to select, falp_60dB is recommended.

Syntax
C#
Visual Basic
public enum TFractionalImpulse : uint { falp_160dB, falp_140dB, falp_140dB2, falp_100dB, falp_60dB, falp_50dB, falp_50dB2 }
