MATLAB: How to shift a filter into higher frequency band filter Hello, Could you please explain how to shift a low pass filter into higher frequency in a Matlab code? For example; how can we make it for a low pass sinc filter? Thanks… Best Answer The following link may be helpful to youhttps://www.mathworks.com/help/dsp/examples/complex-bandpass-filter-design.htmlAlternatively, in theory, a sinc filter is just the Fourier transform of a rectangular window.HTH Related SolutionsMATLAB: Audio Processing Hi Kathik, You have left out an important bit of information and that is the sampling frequency. I'll assume that is 44.1 kHz in this example.In what follows, Hd1 is an FIR equiripple design and H2 is an IIR Butterworth design. I'll use 50 dB of attenuation.d = fdesign.lowpass('Fp,Fst,Ap,Ast',6000,6200,0.5,50,44100);Hd1 = design(d);Hd2 = design(d,'butter');To apply the filter to data, use output = filter(Hd1,input); MATLAB: Do I see the 3-band image in a single band I don't think that should happen. (It would be helpful if you could attach the .png file too)Try the following, incase:imdata = imread('mervveee.png'); RC = imdata(:,:,1); GC = imdata(:,:,2); BC = imdata(:,:,3); im = cat(3,RC,GC,BC); isequal(imdata,im) imshow(im) Related QuestionExtracting a range of pixel values from a specific RGB band
