Answer to Question #281014 in Electrical Engineering for Mig

Question

Determine the impulse response h of the following FIR system:

y[n] = x[n] + 1/2 x[n - 1] + 2x [n - 2] + 4x [n - 3] - x[n - 5]

Answer 1

close all,
clear all,
clc,


y=[];
x=0:1:10;
for n=6:1:length(x)
    if(n<5), y(n)=0; end
    y(n) = x(n) + (1/2)*x(n - 1) + 2*x(n - 2) + 4*x(n - 3) - x(n - 5);
end
