Abstract :
In this paper, the design of digital integrator is investigated. First, the interpolation formula of discrete-time sequence is derived by using discrete Hartley transform (DHT). Then, the numerical integration rules and DHT interpolation are applied to obtain the transfer function of digital integrator. The filter coefficients are easily computed because closed-form design is gotten. Finally, some numerical comparisons with conventional digital integrators are made to demonstrate the effectiveness of this new design approach.
