Abstract

EL DISPOSITIVO CONTROLA LA POTENCIA PICO ACTUANDO SOBRE LA CORRIENTE UMBRAL DEL TRANSMISOR. UN CIRCUITO DE MUESTREO Y RETENCION (SH) MUESTREA LA CORRIENTE SUMINISTRADA POR EL DETECTOR DE MONITORIZACION ASOCIADO CON EL TRANSMISOR, Y UNA UNIDAD DE PROCESAMIENTO (MP) OBTIENE EL VALOR ACTUAL DE LA POTENCIA DE PICO COMO MEDIA DE LOS VALORES ASOCIADOS CON CIERTO NUMERO DE MUESTRAS DE LA CORRIENTE DE MONITORIZACION Y, EN CASO DE DIVERGENCIA ENTRE EL VALOR ACTUAL Y EL VALOR DESEADO, OBTIENE UN VALOR CORRECTO PARA LA CORRIENTE UMBRAL.
