Consider the Z-transform of an impulse response h(n) : H (z )equals fraction numerator 2 minus 2.5 z to the power of negative 1 end exponent over denominator 1 minus 2.5 z to the power of negative 1 end exponent plus z to the power of negative 2 end exponent end fraction. Calculate h(n) if this system is ANTI-CAUSAL.
