Septem EE380 (Control Lab) IITK Lab Manual 0. MATLAB will enable you to study and understand the theory behind signals and systems as well as validate the theory with real-word examples. EX: ramp, Impulse,unit step, sinc- Aperiodic signals Square, sawtooth, triangular sinusoidal – periodic signals. , are chosen as the basis for these exercises because they are widely used by practitioners in the ﬁeld, and because they are capable of realizing interesting systems. By using this website, you consent to the use of cookies.

Systems are operators that accept a given signal (the input signal) and produce a new signal (the output signal). This manual is in part a pedagogical tool concerning the study of signal processing and in part a practical guide to using the signal processing tools available in Scilab. Used to carry message signals in early telephone lines. Scilab offers quite a number of functions for signal processing i. Through-out this lab we will be using MATLAB for the simulation of signals and systems. 20 6 Develop a program for Linear Convolution of two sequences using Scilab.
