Hai everyone, I have an i/p signal x = 1 +0.5* sin(pi*t) where t = [0:0.01:5], basically a signal sampled at 100 Hz. I need to filter out the d.c. component i.e. get 1 as a constant output so for which I have to design a low pass filter.   can any one tel me how to design low pass filter in MATLAB   Thank you

Hi every body, ? I want too plot phase spectrum of a signal. I've used this code: ? X=fftshift(fft(signal)); phi=unwrap(angle(X)); ? But it doesn't work. Although the similar code for amplitude is correct: ? X=fftshift(fft(in)); amp=(abs(X)/2)/max(abs(X)/2); ? ? Can anybody help me? Regards; Rosita

I have a question using soft input vitdec command in matlab. In the example provided by "help" we need to quantize the input like: [x,qcode] = quantiz(1-2*ncode,[-.75 -.5 -.25 0 .25 .5 .75],... [7 6 5 4 3 2 1 0]); % Values in qcode are between 0 and 2^3-1. decoded3 = vitdec(qcode',trel,tblen,'cont','soft',3); my question is how to choose the interval? (in this example it is [-.75 -.5 -...

I have 100 text files,namely,file000.txt, file001.txt ,....,file099; total of 19 text files. What I would like to do is to read these 100 files using textscan function of MATLAB into matrices like f(:,1),f(:,2),....,f(:,99). Can anybody help me figure out how can I do this without having writing textscan 100 times? Thank you very much for any help you may provide. Sincerely, S

Hi All, I have a set of noise data , x= [1 2 3 4 5 6 ]. I want to add additive white Gaussian noise to it using g= x+ 0.5* rand(1,6) How do i calculate the signal to noise ratio of this signal if the variance of the rand is 0.5. I know the relationship between SNR and variance, mathematicallly and can implement that in MATLAB. Is there any function that can calculate that easily ...
