Computing the Spectrum of Discrete-Time Signals Using the FFT Command

Utilizing the FFT command in MATLAB functions to compute the spectrum of discrete-time signals, enhancing understanding of Discrete Fourier Transform (DFT) for discrete signals and the application of the Fast Fourier Transform (FFT) algorithm. The implementation involves generating signal vectors, applying FFT with proper scaling, and plotting magnitude/phase spectra using functions like fft(), fftshift(), and abs().
