Magnitude Specifications Region: Bandstop 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:

• Ripple in the first passband (Apass1 or Dpass1)
• Stopband attenuation (Astop or Dstop)
• Ripple in the second passband (Apass2 or Dpass2)

Magnitude Specifications Region: Bandstop Least-Squares
