WebMar 6, 2024 · Hello, I am a new MATLAB user. I had a function which I did Fourier Transform for, and the result was: X(w)=1/(1+jw) where w is the frequency and " j " is the known imaginary number. I would like to know what code I should input in MATLAB in order to plot the phase and amplitude spectra of X(w). Thanks in advance... WebOptical systems implementing 1,2, and 3 qubits discrete Fourier transform (DFT) are described, and a general method for implementing the n-qubit DFT is analyzed. These transformations are used on various input radiation states by which phase estimation and order finding can be computed.
