public float CentralFrequency { get; set; }

The CentralFrequency property specifies the frequency about which the filter zone is centered. The value is normalized to the Nyquist frequency and must therefore have an absolute value ranging from 0.0 to 1.0. If a value of 0.0 is specified, the filter zone is centered at the DC term of the data's frequency spectrum. If any other positive or negative value is specified, the filter zone is centered at that frequency and automatically mirrored into the ooposing sign frequencies. See the DirectionalFrequencyFilter topic for an illustration of the filter geometry.
