Determine the impulse response for the cascade of two LTI systems having impulse responses h1(n)=\((\frac{1}{2})^2\) u(n) and h2(n)=\((\frac{1}{4})^2\) u(n).

\((\frac{1}{2})^n[2+(\frac{1}{2})^n]\), n<0

\((\frac{1}{2})^n[2-(\frac{1}{2})^n]\), n

\((\frac{1}{2})^n[2-(\frac{1}{2})^n]\), n>0

\((\frac{1}{2})^n[2+(\frac{1}{2})^n]\), n

\((\frac{1}{2})^n[2+(\frac{1}{2})^n]\), n>0
