Signal Processing Toolbox

Choosing a Filter Type

You can choose from several filter types:

• Lowpass
• Highpass
• Bandpass
• Bandstop
• Differentiator
• Hilbert transformer
• Multiband
• Arbitrary magnitude
• Raised cosine

Additional filter types are available if you have the Filter Design Toolbox installed.

To design a bandpass filter, select the radio button next to Bandpass in the Filter Type region of the GUI.

Note    Not all filter design methods are available for all filter types. Once you choose your filter type, this may restrict the filter design methods available to you. Filter design methods that are not available for a selected filter type are removed from the Design Method region of the GUI.
