Abstract
SISTEMA DE TELEMEDIA. UN CONJUNTO EMISOR SE SITUA PROXIMO A UN SENSOR (1), EL CUAL PROPORCIONA UNA SEÑAL DE BAJO NIVEL QUE MODULA UNA SEÑAL PROPORCIONADA POR UN MODULADOR (2), PARA QUE FINALMENTE UN TRANSMISOR (3) EMITA UNA SEÑAL, PORTADORA DE RADIOFRECUENCIA, MODULADA POR EL SENSOR. UN CONJUNTO RECEPTOR SITUADO A UNA CIERTA DISTANCIA TRATA LA SEÑAL RECIBIDA, DANDO SU INFORMACION A UN EQUIPO DE MEDIDA.
