INTRODUCTION
The workbook is designed for the students of Department of Computer and Information Systems
Engineering, NED University of Engineering and Technology enrolled in the subject of Signals and
Systems. The new version of the workbook is made to accommodate the requirement of Objective
Based Education (OBE). Four lab sessions are directly mapped on CLO-3 ‘Practice simulation of
signals and systems using modern tools’. The taxonomy level is P-3. The CLO has been mapped to
PLO-5, ‘modern tool usage’ which includes lab session 6, 7, 8 and 9.
The workbook is divided in three basic sessions. The first session of the workbook which is from lab
session 1 to lab session 5 is to aid student to understand signal processing on MATLAB software. The
second session is to design electronic circuits for signal processing. This session is mapped onto
CLO-3 as stated above. The third and final session is related to Simulink models for basic signal
processing.
