Magnitude Specifications Region: Lowpass Window

If Specify order is selected in the Filter Order region, the attenuation at the cutoff frequency is fixed at 6 dB (half the passband gain).

For the Kaiser window option, 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 Least-Squares

Magnitude Specifications Region: Highpass Butterworth
