window.m.zip - This script calculate the Fourier transform of a Rectangular window of 64 points
using an aproximation with a DFT of 1024 points,as well as calculates for differents values of f0 and f1 the module of the frecuency response of the windowed signal. All of this is for "look" the windowed effect.

satlink_calculus.m.zip - Satlink calculus is a script to realice the process of calculus of an link occuped by a transponder to multiple low carriers capacity considering certain parameters and esentials characteristics of the net. This program resolves the exercise from figure 3.14 pag. 130 from the book."Comunicaciones por Satélite" of Carlos Rosado.

IIRButterworthfilter.m.zip - Script to design an IIR Filter low pass using Butterworth & lineal transformation to convert
from analogic to digital a prototype filter.
by actinio vjgonzalezg@gmail.com :)
It plots:
1-Frecuency response of the filter impulse.
2-Magnitude response of the filter.
3-phase of the frecuency response.
4-Error of aproximation in bands.
It determines error of máximun aproximation on each band and the RMS value for the reject and pass band respectively
then, obtains plots of the first 50 samples for the following entries:
a)An rectangular pulse as the half of the longitud of the filter in n=0
b)A senoidal wave with amplitude =1 & frecuency 0.2 Fs.
c)A senoidal wave with amplitude = 1. & frecuency= 0.25 Fs.
d)A senoidal wave with amplitude = 1. & frecuency= 0.375 Fs.

FIRWindowstechnique.m.zip - Script for designing FIR filter low pass with lineal phase & cut-frecuency equal to obtained from
a IRR Filter.
Windows used:
a)Rectangular window.
b)Hamming window.
c)Kaiser window.
"Calculus of the windows are obtained from commands hamming, boxcar & kaiser."
Magnitude and frecuency response of the FIR filter are generated for each window tecnhique applied.

aliasing_for_time_domain_signal.m.zip - This package contains script to calculate aliasing for given time domain signal. Script to plot in time domain the function: x(t)=A0cos(2pif0t)+A1cos(2pif1t)
where fs1=300 Hz and fs2=150 Hz (sampling rate)
A0 and A1 are amplitude s signal (armónicos).
f0 is the maximun component in frecuency of the signal to sample,
when it shows X(t) signal with a sampling frecuency 300 Hz,
we will see Aliasing :)
It s because we aren t meetting with the Nyquist Theorem, because we don t choice Fs>=2FNy Fs(Sampling Frec) FNy(Frec Nyquist) to sample aplying fft(fast fourier transform) with at least 600 Hz.
