Experimental evaluation of distortion in amplitude modulation techniques for parametric loudspeakers
(MDPI, 2020) info:eu-repo/semantics/article,
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 ...
Analysis of singular one-dimensional linear boundary value problems using two-point Taylor expansions
(University of Szeged (Hungría), 2020) info:eu-repo/semantics/article,
We consider the second-order linear differential equation (x2 − 1)y'' + f (x)y′ + g(x)y = h(x) in the interval (−1, 1) with initial conditions or boundary conditions (Dirichlet, Neumann or mixed Dirichlet–Neumann). The ...
