New perspectives for modeling the pulse width modulation. Some application for audio systems

The main purpose of this paper is to introduce an alternative theoretical approach for modeling the Pulse Width Modulation (PWM). Even though in this present moment inside the world of new technologies, we have been assisting a great transition between the modern analog architectures for some similar ones, which have the whole design built with digital clothing; in some cases many projects that use the analog design have an expressive better performance if we compare with the second one. We check the technological technique presented here, with some simulations that permit us to see a direct application of this approach in the design for modern Audio Systems.
