Generation of sinusoidal analog carriers through rectangular waveforms as a new proposal to introduce the digital modulation

The essential purpose of this paper is to present how to synthesize a sinusoidal wave by using a sum of square waveforms. The process that the AC signal is generated permit to calculate all coefficient and essential parameters involved in the numerical process of convergence and it is possible to proceed an accurate adjustment on the final form of the analog wave. The principal and important application we can derive from this study is the introduction of a new concept of digital modulation.
