In this laboratory, the concept of analog to digital signal conversion as well as time and frequency domain analysis of digital signals using MATLAB software are studied. Students can implement the theory learned in Digital Signal Processing and design an optimal analog to discrete signal converter. Besides, they can analyze the time domain as well as frequency domain characteristics by plotting the output signal in the MATLAB window. The experience the students gain in this lab will be later helpful for those who want to build their career in the communication sector.
