Abstract

Un sistema sintonizador automático de antena para el sistema de identificación de radiofrecuencia incluye un modulador del ancho de pulso, un microprocesador para controlar la generación de una señal de fuente desde el modulador, condensadores para recibir la señal de fuente desde los amplificadores y transmitirla a un inductor, una puerta que se comunica con los condensadores para transmitir una señal resonante desde el inductor y los condensadores como una señal portadora, y medios para controlar la señal portadora con la señal de fuente para producir una señal comparada para producir una secuencia de pulsos, y medios para variar la capacitancia para aumentar o disminuir el conteo de la secuencia de pulsos.
