How do you find impulse response and step response for the function
y(n) = (3/5)^(n)y(n-1) + x(n) for 0<n<20 discrete
This is what i have, can someone help me for n=0:20;
imp = [1; zeros(20,1)]; step = 1;
b = 1;
a = [1 -0.6*exp(n)];
h = filter(b,a,imp);
m = filter(b,a,step);
plot(n,h);
plot(n,m);
end
