Multi-channel Software-Oriented Pulse Width Modulation (SPWM)
نویسنده
چکیده
In this paper, we propose a software-oriented method for generating multiple pulse width modulation channels from the parallel port of a computer without using any additional interface. We have developed an algorithm to modulate different signals that may come from different sources and generate the corresponding modulated signals on the parallel port of a computer. Our approach is tested in real-word applications, and the successful results open the door for relying more and more on software for the different types of modulation and various telecommunication systems like software radio.
