Signal Processing Toolbox

Magnitude Specifications Region: Lowpass Equiripple

If Specify order is selected in the Filter Order region, specify the following relative weights in the text boxes:

• Passband weighting (Wpass)
• Stopband weighting (Wstop)

If Minimum order is selected in the Filter Order region, select the units for magnitude response characteristics from the Units list:

• dB for magnitude response characteristics in decibels (default)
• Linear for linearly scaled magnitude response characteristics

Specify the following magnitude response characteristics in the text boxes:

• Passband ripple (Apass or Dpass)
• Stopband attenuation (Astop or Dstop)

Magnitude Specifications Region: Lowpass Elliptic

Magnitude Specifications Region: Lowpass Least-Squares
