How do you shift frequency in MATLAB?
In Matlab you can use the fftshift() command. It will rearrange the samples so that the frequency range is between −fs/2 and fs/2.
How do you find the central frequency in MATLAB?
Center Frequencies of Channelizer
Frequency in Hz, f, equals f = ( ω / 2 π ) × F s , where w is frequency in radians, and Fs is the sampling rate.
Why use Fftshift in MATLAB?
command fftshift is used to visualise the FFT within [-Fs/2 Fs/2] instead of [0 Fs] that is the interval that the FFT takes as default.
