Abstract :
In this paper, the design of digital integrator is investigated. First, the Stancu polynomial is described. Then, non-integer delay sample estimation of discrete-time sequence is derived by using Stancu polynomial. Next, the numerical integration rules and non-integer delay sample estimation are applied to obtain the transfer function of digital integrator. Finally, some numerical comparisons with conventional digital integrators are made to demonstrate the effectiveness of this new design approach.
