- •
α-spline pulses. Convolution in the frequency domain.
- •
Mathematical consistency to use positive real numbers, instead of natural numbers.
- •
Digital filters are designed with a flat behavior in the passband.
- •
Closed form expressions for the responses of the proposed filters are derived.
- •
Simulation results show that our approach yields superior filter characteristics.
