Magnitude Specifications Region: Bandpass Elliptic

If Specify order is selected in the Filter Order region, specify the following magnitude response characteristics (in dB) in the text boxes:

• Stopband attenuation (Astop)
• Passband ripple (Apass)

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)
• Squared for squared magnitude response characteristics

Specify the following magnitude response characteristics in the text boxes:

• Attenuation in the first stopband (Astop1or Estop1)
• Passband ripple (Apass or Epass)
• Attenuation in the second stopband (Astop2 or Estop2)

Magnitude Specifications Region: Bandpass Chebyshev Type II
