Abstract
LA CIRCUITERIA DEL FILTRO FIR PARA EL PROCESAMIENTO DE SEÑALES MUESTREADAS, MULTIPLEXADAS DE DIVISION DE TIEMPO, INCLUYE CONJUNTOS PARALELOS DE ELEMENTOS DE RETARDO (DSP,DHP), PARA RETRASAR LAS SEÑALES RESPECTIVAS A FILTRAR, CADA CONJUNTO TIENE UNA PLURALIDAD DE DERIVACIONES. LAS DERIVACIONES CORRESPONDIENTES DE LOS RESPECTIVOS CONJUNTOS DE ELEMENTOS DE RETARDO SE ACOPLAN A UNA ESTRUCTURA COMPENSADORA (WN+I) Y SUMADORA COMUN. LA SEÑAL MULTIPLEXADA DE DIVISION DE TIEMPO SE ACOPLA A LOS CONJUNTOS PARALELOS DE ELEMENTOS DE RETARDO, LOS CONJUNTOS RESPECTIVOS SON EXCLUSIVAMENTE SINCRONIZADOS (DSP, CLK, DHPCLK) SOBRE LA OCURRENCIA DE LAS SEÑALES CORRESPONDIENTES.
