Direct form-II realization has the advantage that, it uses minimum number of integrators. Instead of using separate integrators for integrating the input and output variable separately, an intermediate variable is integrated. The following examples illustrate the procedures to obtain direct form-II realization of continuous-time system described by the transfer functions or differential equations.

A system is defined as an entity that acts on input signal and transforms it into an output signal. The most two attributes of a system are linearity and time invariance. A system which is both linear and time invariant is caused a linear time invariant (LTI) system.
