All-Pole Recursive Digital Filters Design Based on Ultraspherical Polynomials [PDF]
Radioengineering, 2014 A simple method for approximation of all-pole recursive digital filters, directly in digital domain, is described. Transfer function of these filters, referred to as Ultraspherical filters, is controlled by order of the Ultraspherical polynomial, nu ...

Acoustooptic digital filter [PDF]
Applied Optics, 1985 Digital filters have three components: (1) unit delays, (2) multipliers, and (3) adders. These components can be implemented by using (1) a Bragg cell as a tapped delay line, (2) optical multiplication using the Bragg cell transmittance, and (3) photodetectors.
