Signal Processing Toolbox

Frequency Specifications Region: Bandstop Window

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
• First cutoff frequency (Fc1or wc1) - the frequency preceding the stopband at which the magnitude response is 6 dB below the passband gain
• Second cutoff frequency (Fc2 or wc2) - the frequency following the stopband at which the magnitude response is 6 dB below the passband gain

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 first passband (Fpass1 or wpass1)
• Beginning of the stopband (Fstop1 or wstop1)
• End of the stopband (Fstop2 or wstop2)
• Beginning of the second passband (Fpass2 or wpass2)
