Abstract

LA INVENCION SE REFIERE A LA FORMACION DE UN IMPULSO DE CONTROL PARA EL TRANSMISOR EN UN SISTEMA DE RADIOTELEFONO GSM. SE FORMA UN IMPULSO DE COS2 MEDIANTE UN CIRCUITO ANALOGICO DESDE UN IMPULSO RECTANGULAR, QUE PRIMERO SE CONFIGURA EN UN IMPULSO TRIANGULAR, QUE PUEDE ESTAR ALGO RECORTADO EN SU PICO. EL IMPULSO TRIANGULAR SE CONFIGURA DESPUES A UN IMPULSO DE COS2. EL CIRCUITO INCLUYE TAMBIEN MEDIO PARA USAR CON LAS DESIGUALDADES DEL IMPULSO TRIANGULAR Y CON ELLO PUEDEN SELECCIONARSE LAS CITADAS DESIGUALDADES DEL IMPULSO DE COS2.
