This article may be used for non-commercial purposes in accordance with Wiley Terms and Conditions for Use of Self-Archived Versions.A technique for the reduction of third-order intermodulation distortion (IMD3) occurring in bulk acoustic wave (BAW) filters and multiplexers is presented. The method consists of using the intrinsic second-order intermodulation distortion generated by BAW filters and multiplexers themselves by injecting an externally controlled amplitude and phase modulated signal at low frequency to compensate for the IMD3. The proposed technique has been experimentally verified by performing IMD3 measurements in a single BAW resonator subject to several modulated signals under a nonlinear scenario.Secretary of Universities and Research of the Generalitat de Catalunya and the European Social Fund, Grant/Award Number: FI_B-00136; Spanish Government, Grant/Award Numbers: 2017 SGR-813,TEC2017-84817-C2-2-R, TEC2017-88343-C4-2-RPeer ReviewedPostprint (author's final draft

Buenas prácticas : Apertura de Centros a la Comunidad

Recopilación de 'Buenas Prácticas' presentadas en el Seminario Regional de Apertura de Centros celebrado en el Instituto de Educación Secundaria Carreño Miranda de Avilés en septiembre de 2006. A través de las propuestas de quince centros educativos asturianos, la publicación permite aproximarnos a diversas concepciones en el diseño y desarrollo del programa de Apertura de Centros a la Comunidad. La presentación de estos proyectos se realiza en torno a cuatro áreas: Participación, Promoción de la salud, Compensación de desigualdades, y Familia-Escuela.AsturiasUniversidad de Oviedo.
