State space analysis is an excellent method for design and analysis of control system. It can be applied to Nonlinear, Time-invariant and MIMO systems. Proposed research work has presents a state space description for the
minimal delay wavelet FIR filter banks by using special orthonormal basis function. This FIR structure guarantees BIBO
stability, Robustness and provide Perfect reconstruction by verifying the Minimality, observability, and the minimal
realization for the filter transfer function. Also proposed work has lesser delay compared to base research work
