Experimental Evaluation of Distortion in Amplitude Modulation Techniques for Parametric Loudspeakers

Autor: Ricardo San Martín, Pablo Tello, Ana Valencia, Asier Marzo

Publikováno v: Applied Sciences, Vol 10, Iss 6, p 2070 (2020)

Parametric loudspeakers can generate a highly directional beam of sound, having applications in targeted audio delivery. Audible sound modulated into an ultrasonic carrier will get self-demodulated along the highly directive beam due to the non-linea

International audience; The aim of this paper is to analytically evaluate the spectral regrowth at the output of a transmitter due to the nonlinear components such as the power amplifier (PA). Therefore, we propose a generalization of existing closed
