Signal Processing Toolbox

Frequency Specifications Region:
Lowpass Chebyshev Type I

Select the units for frequency specifications from the Units list:

• Hz (default)
• kHz
• MHz
• Normalized (0 to 1), where 1 corresponds to the Nyquist frequency

If Specify order is selected in the Filter Order region, specify the following frequencies in the text boxes:

• Sampling frequency (Fs) - required when Hz, kHz, or MHz is selected
• End of the passband (Fpass or wpass)

If Minimum order is selected in the Filter Order region, specify the following frequencies in the text boxes:

• Sampling frequency (Fs) - required when Hz, kHz, or MHz is selected
• End of the passband (Fpass or wpass)
• Beginning of the stopband (Fstop or wstop)

Frequency Specifications Region: Lowpass Butterworth
