Magnitude Specifications Region: Bandpass Window

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

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:

• Attenuation in the first stopband (Astop1 or Dstop1)
• Passband ripple (Apass or Dpass)
• Attenuation in the second stopband (Astop2 or Dstop2)
