Matlab has no “dft” feature, because the FFT computes the DFT precisely. Only the significance of the FFT is stored, even though the phase of the FFT is useful is a few applications. The “fft” function lets in the range of factors outputted through the FFT to be unique, but for ...

I am trying to understand basic fft functions of a shifted time series and my graphs are not appearing as I expect them to:To plot the FFT of a shifted time series and understand its behavior, it is important to ensure that the time and frequency domains are correctly handled. The curr...

Open in MATLAB Online For an analysis I have the following script. Everything is fine and working. My Prof now wants to know the central frequeny out of the fft. How di I get the central frequency? ThemeCopy Fs= 1.9* 10^6 ; %sampling frequency T = 1/Fs; %sampling period L...
theoremYes,I know its convolution :) (that's what I asked),and I know how to do it ...
Could u put it a different way. Or may be let me rephrase what i was asking. In matlab using fft command to requires us to enter the number of points(for eg 512) for fft as an argument and the result of fft is 512 points So when I plot it using plot(x,y) ...
how to do convolution without commandsThis is a little more complex than necessary - you don't need the first loop that reflects A, just change the index computation in the second loop to reflect the mathematical definition of convolution.You...
2. then I apply a Kaiser window on freq domain. 3. I do an IFFT of my response and plot them against time (here time is the inverse of the freq points). 2. Then I apply time gate and do FFt back to freq domain and I lose the responses of outside the time gate in freq domai...
