This paper presents an innovative theoretic and numerical approach for modeling the classic pulse introduce by Nyquist, which is a very important a digital modulation that one of the main stakes of the area of digital signal processing. An appropriate revision over concept of Operational Window Aperture with the purpose to check our approach by applying it over the Raised Cosine pulse, and as a direct consequence will permit to reach our final objective. A complementary revision will be made over the new concept of a digital modulation introduced by the authors previously which was defined as the Rise Time Modulation (RTM) since part of this technological approach will be concerned in this paper. The technique adopted for modeling both full and half pulses can be applied for a wide class of digital transmission systems which demand an appropriate modeling for all communication channels. Some considerations will be performed to present a Nyquist pulse with distinct two roll off factors, that can results the optimization of the interference as well as the intrinsic noises that appear in those systems with a very high transmission rates.

The theoretical and numerical analysis proposed in this paper is totally original and the essential purpose is to introduce an innovative procedure to represent some of the more important digital communications signals by using a simple mathematical tool. All new analytical concepts presented here can be used as de¯nitions of these signals and the great improvement is the fact that we can manipulate all of them through some°exible as well as original mathematical operations. This theoretical technique permits us to represent all classic analogical waves by using periodic and non-periodic continuous functions such that they can be seen as a video color signal or a simple sequence of zeros and ones. By using a nonlinear operator, it is possible to de¯ne analytically a wide class of important electromagnetic waves.

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.
