Program Matlab NRZ Unipolar

Berikut ini merupakan program membuat gelombang NRZ Unipolar dengan Matlab :

Listing program :

bit = [1 0 1 0 0 0 1 1 0];
bitrate = 1; % bits per second

figure;
[t,s] = unrz(bit,bitrate);
plot(t,s,'LineWidth',3);
axis([0 t(end) -0.1 1.1])
grid on;
title(['Unipolar NRZ: [' num2str(bits) ']']);

Dan berikut keluaran dari program diatas :

Program Matlab untuk NRZ-M PCM Waveforms

Berikut merupakan program untuk membuat program Matlab NRZ-M :

%NRZ-M

clear all;clc;

x=[1 0 1 1 0 0 0 1 1 0];    %matriks inputan x

n=length(x);    %mendapat jumlah isi var x

t=0:1/16:n-1/16;    %mengatur sampling

x(1)=1;

xx=x;

for k=2:n;

    if x(k-1)==0 & x(k)==1;

        xx(k)=-1;

    end

end

m=xx;

for k=1:n;

    if xx(k)==0;

        m(k)=1;

    end

end

p=ones(16,1);     %matriks 16x1 yg berisi nilai 1

a=p*m;

d=reshape(a,1,[]);

z=d;

figure(1)

subplot(211)

plot (t,d);title('NRZ-M')

axis([0 10 -2 2])

grid on

subplot(212)

s=fft(d,1024);

 f=0:1024-1;

plot(f,20*log10(abs(s)))

axis([0 1024 -60 40])

grid on
