Parameter | Value | Description |
---|---|---|
Coefficient Options | ||
Symmetry | Non Symmetry Symmetrical Anti-Symmetrical |
Specifies whether your filter design uses non-symmetric, symmetric, or anti-symmetric coefficients. The default value is Non Symmetry. |
L-th Band Filter | All taps Half band 3rd–5th |
Specifies the appropriate L-band Nyquist filters. Every Lth coefficient of these filters is zero, counting out from the center tap. |
Coefficient Scaling | Auto None |
Specifies the coefficient scaling mode. Select Auto to apply a scaling factor in which the maximum coefficient value equals the maximum possible value for a given number of bits. Select None to read in pre-scaled integer values for the coefficients and disable scaling. |
Coefficient Data Type | Signed Binary Signed Fractional Binary |
Specifies the coefficient input data type. Select Signed Fractional Binary to monitor which bits are preserved and which bits are removed during the filtering process. |
Coefficient Width | 2–32 | Specifies the width of the coefficients. The default value is 8 bits. |
Coefficient Fractional Width | 0–32 | Specifies the width of the coefficient data input into the filter when you select Signed Fractional Binary as your coefficient data type. |
