New crossover network based on q-bernstein polynomial

Abstract

This paper presents a new audio crossover network based on q-Bernstein polynomial which can be adjustable attenuation in stop-band by varying parameters of the transfer function. The crossover network gives an in-phase response and a flat summed of magnitude response of each filter through audio frequency band. The simulation results shown that the crossover network given high attenuation in stop-band which better than conventional crossover network at second-order and fourth-order. Moreover, the crossover network structure can be reduced complexity by based on subtractive circuits. Therefore, the proposed crossover network provided a high quality crossover network and can useful for professional reproduction sound systems.
