Magnitude Specifications Region: Lowpass Elliptic

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

• Passband ripple (Apass or Epass)
• Stopband attenuation (Astop or Estop)

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:

• Passband ripple (Apass or Epass)
• Stopband attenuation (Astop or Estop)

Magnitude Specifications Region: Lowpass Chebyshev Type II

Magnitude Specifications Region: Lowpass Equiripple
