Abstract
In the following publication demonstrates the construction and use of the sync filter,which will have the income of any waveform, square waves, sine waves or triangle waves, the same that will be modeled on a kernel with math formulas.
For this we must define the variables to enter thekernel, and once have entered the formula we obtain the output waveform that is displayed in frequency, in terms of convolution must generate a certain number of samples to be combined them withfrequency values ​​to form the convolution.

1. Introduction

The use of the kernel to enter the mathematical formula helps a signal represented in the plane of the time to convert in frequencyplane. Manipulating the value of the constant M can vary the pulse width value of the output signal of the kernel, same thing happens with fc. In other to generate a number of data representing a timevalue for the space of a given pulse, and the two combined data can be the convolution of the signal to obtain the time domain.

2. Design Processing

* Labview
* DAQ

2.1Schematic Design
In the following block diagram represents the way we obtain the output signal will be combined with the generation of obtaining points that represent a time value. With thecombination of the both the convolution signal is obtained:

2.3 Processes

2.3.1 Front Panel
As we appreciate the front panel is divided in 6 spaces, two of then display the wave form graphs, otherstwo represents the source mode, manipulation of attenuation and filter, on the writhe side is displayed the data and under this are the control of simulated signal. In the next figure we show thedesign of our front panel.



2.3.2 Data Acquisition

In our case we have two ways to acquired signals, the first one is simulated and the second one is a real, which comes through the...
