Signal Processing Toolbox

Magnitude Specifications Region:
Lowpass Chebyshev Type I

If Specify order is selected in the Filter Order region, specify the passband ripple (Apass or Epass) in decibels.

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 Butterworth

Magnitude Specifications Region: Lowpass Chebyshev Type II
