Homework Statement
Work out the correct coefficient arrays for these equations:
y(n)=y(n-1)+[itex]\frac{1}{5}[/itex](x(n)-x(n-5))
y(n) = 0.82y(n -1) + .28x(n)
Homework Equations
[itex]\sum a(r)y(n+1-r)[/itex]=[itex]\sum b(k)y(n+1-k)[/itex] where a(1) = 1
The Attempt at a Solution
Ok for the second equation the coefficients are clearly 0.82 and 0.28, now if I were to put that in an array for MATLAB would it be [0.82 0 0 0 0] and [0.28 0.28 0.28 0.28 0.28]?
For the first equation I have no idea how to go about finding the coefficients.
Cheers for any help.
