2 dimensional filter design using mcclellan transformation in matlab

The following Matlab project contains the source code and Matlab examples used for 2 dimensional filter design using mcclellan transformation. [Filter_1D,Filter_2D]=Filter_Design_2D_McClellan(Type,edges,Ap,Aa,transformation_vector) This function can be used to design a lowpass, highpass, bandpass, or bandstop two-dimensional filter which satisfies prescribed specifications.

Low Pass Filter Matlab Code

A low-pass filter is a filter that passes low-frequency signals and attenuates (reduces the amplitude of) signals with frequencies higher than the cutoff frequency. The actual amount of attenuation for each frequency varies depending on specific filter design. It is sometimes called a high-cut filter, or treble cut filter in audio applications. A low-pass filter is the opposite of a high-pass filter. A band-pass filter is a combination of a low-pass and a high-pass.
