    Sampling in Matlab

    Uploaded by

    Engr. Naveed Mazhar
    This document contains MATLAB code that performs sampling on a cosine signal with different sampling frequencies. It generates a cosine signal, samples it using different sampling frequencies corresponding to different ratios of the original signal frequency, and plots the original, sampled, and reconstructed signals. It contains 3 sections that sample the cosine signal at frequencies corresponding to ratios of 2/3, 4/3, and 2/5 of the original signal frequency.
