Abstract

CIRCUITO DE DIEZMADO Y PROCEDIMIENTO PARA EL FILTRAJE DE SEÑALES CUANTIFICADAS, PROPORCIONANDO AL MISMO TIEMPO UNA CORRECCION DEL ANGULO DE DESFASAMIENTO CON UNA RESPUESTA DE FASE SUSTANCIALMENTE LINEAL. CIRCUITO DE DIEZMADO PARA FILTRADO DE UN FLUJO DE SEÑALES ELECTRICAS CUANTIFICADAS, PROPORCIONANDO UNA CORRECCION DEL ANGULO DE DESFASAMIENTO Y RESPUESTA DE FASE SUBSTANCIALMENTE LINEAL SOBRE UNA GEMA DE LA BANDA DE PASO FB. EL FLUJO DE SEÑALES ELECTRICAS LLEGA A UN REGIMEN FM PREDETERMINADO DESDE UN MODULADOR DELTA-SIGMA DE SOBREMUESTREO. EL CIRCUITO COMPRENDE UN FILTRO DE DIEZMADO PARA FILTRAR EL FLUJO DE SEÑALES ELECTRICAS, PARA PROPORCIONAR UNA SEÑAL DE SALIDA FILTRADA A UN REGIMEN DE SALIDA F''S = FM/R, DONDE R ES UN ENTERO POSITIVO. EXISTE UN CORRECTOR DE FASE ACOPLADO AL FILTRO DE DIEZMADO PARA RECIBIR LA SEÑAL DE SALIDA FILTRADA Y CORREGIR EL ANGULO DE DESFASAMIENTO, PARA PROPORCIONAR UN ANGULO ECUALIZADO. EL VALOR DE R SE SELECCIONA DE FORMA QUE EL REGIMEN DE SALIDA F''S ESTE SITUADOPOR ENCIMA DE LA BANDA DE PASO FB, PARA QUE EL CORRECTOR DE FASE PROPORCIONE LA RESPUESTA DE FASE SUSTANCIALMENTE LINEAL EN LA GAMA DE LA BANDA DE PASO FB.
