Question

If the input signal x(n) =[1,2,3,82,82,82,82,82,4, 5,6] plot x(2n+3) in Matlab.
What is the code of the above signal?

Answer 1

Matlab code

clc
clear all
n=0:1:10;
x=[1,2,3,82,82,82,82,82,4, 5,6];
figure(1)
subplot(2,1,1),stem(n,x);
title(' Discrete time signal');
xlabel('Time(s)');
ylabel('Sampled signal(volts)');

%shifted and scaled signal
n1=2*n+3;
subplot(2,1,2),stem(n1,x);
title(' Shifted and scaled Discrete time signal');
xlabel('Time(s)');
ylabel('Sampled signal(volts)');
