What is the causal inverse of the FIR system with impulse response h(n...
Explanation: Given h(n)= δ(n)-aδ(n-1)
Since h(0)=1, h(1)=-a and h(n)=0 for n≥a, we have
hI(0)=1/h(0)=1.
and
hI(n)=-ahI(n-1) for n≥1
Consequently, hI(1)=a, hI(2)=a2,….hI(n)=an
Which corresponds to a causal IIR system as expected.

The causal inverse of an FIR system with impulse response h(n) is the system with impulse response h'(n) such that the convolution of h(n) and h'(n) is equal to the impulse response of an ideal unit delay. In other words, h'(n) is the impulse response that, when convolved with h(n), results in a unit impulse response shifted by one time unit.
