For the following system: y(n)-y(n-1)/() a=x(n), for a=0.85, find y(4), assuming y(n)=0, for n<=-1. [Hint: find a closed form for y(n) and use it to find the required output sample. for n>=0.
For the following system: y(n) - y(n - 1).
a = x(n), for a = 0.85, find y(4), assuming
y(n) = O, for ns -1. [Hint: find a closed
form for y(n) and use it to find the
required output sample. (x(n)=1 for
n>=O)].
