An Investigation on Scilab Software for the Design of Transform Techniques and Digital Filters

The utilization of open and free-environment programming has increased drastically in education and research fields in the current pandemic situation. SCILAB programming originated from a laboratory INRIA in France and it is the overall open and free-environment reference in mathematical calculation programming. It is an alternative open-source with an easy syntax to the licensed software MATLAB. This preliminary study paper describes about the design and simulation of the discrete-time signal processing laboratory concepts with the SCILAB open-source software. The transform techniques in signal processing like Fourier Transform of discrete signals, fast Fourier Transform, Fourier series for discrete-time periodic signals and digital filters are better understood with the simulation results obtained in SCILAB. The student feedback shows that the student attention has improved with SCILAB based signal processing teaching.
