Abstract

SE PROPONE UN DISPOSITIVO PARA LA GENERACION DE UNA SEÑAL MODULADA DE ANCHURA DE IMPULSOS (19), LA CUAL ES DERIVADA DE UNA PRIMERA SEÑAL MODULADA DE ANCHURA DE IMPULSOS (11), EN EL QUE LA DURACION DEL PERIODO (25) DE LA SEGUNDA SEÑAL (19) ES NOTABLEMENTE MAS CORTA QUE LA DURACION DEL PERIODO (20) DE LA PRIMERA SEÑAL (11). LA PRIMERA SEÑAL (11) ES PUESTA A DISPOSICION POR UN MICROPROCESADOR (10). LA SEGUNDA SEÑAL DE ALTA FRECUENCIA (19) ES EMITIDA POR UN COMPARADOR (18). UNA CONSIDERABLE VENTAJA DEL DISPOSITIVO OBJETO DE ESTA INVENCION, ES SU REALIZACION A COSTES MUY FAVORABLES.
