Lab-4

The fourth lab was about sampling and reconstruction. An input signal is sampled at regular intervals. The sampling theorem needs to be satisfied. According the sampling theorem the sampling frequency needs to be greater than or equal to twice the maximum frequency present in the signal. If this is not taken care of then we observe aliasing effects. Reconstruction is not possible if this theorem is not satisfied. This experiment was performed on MATLAB. Also the graphs were plotted to illustrate the experiment.
