Linear Phase Mixed FIR/IIR Crossover Networks: Design and Real-Time Implementation

Crossover networks are crucial components of audio reproduction systems and therefore they have received great attention in literature. In this paper, the design and implementation of a digital crossover will be presented. A mixed FIR/IIR solution has been explored in order to exploit the respective benefits of FIR and IIR realizations, aiming at designing a low delay, low complexity, easily extendible, approximately linear phase crossover network. A software real-time implementation for the NU-Tech platform of the proposed system will be shown. Practical tests have been carried out to evaluate the performance of the proposed approach.
