MATLAB is an interactive system whose basic data element is an array that does not require dimensioning. This allows you to solve many technical computing problems, especially those with matrix and vector formulations, in a fraction of the time it would take to write a program in a scalar noni...
This article presents Scilab code that allows you to generate I/Q, noise, and chirp signals from your PC’s headphone jack. In my previous article, we discussed how to use your computer as an arbitrary wave generator via a technique whereby numerical signals are created in a co...
In this article, we’ll convert a sound file into a typical Scilab data array and then perform frequency modulation using this real-life data as the baseband signal. This should be a valuable exercise for those who are interested insoftware-defined radios. When we generate a digiti...
