Abstract
UN BANCO FILTRADOR DIGITAL PARA REDUCIR EL CONSUMO DE POTENCIA POR REDUCCION DEL NUMERO DE MULTIPLICACIONES PORTADAS SOBRE EL. AQUI SE PROPONE PARTICULARMENTE UN BANCO FILTRADOR PARA USO EN APLICACIONES DE ACUMULADORES. EL BANCO DE FILTRADO DIGITAL INCLUYE UN FILTRO [H1(Z)] BASICO DIGITAL RELLENO CON CEROS QUE TIENE UNA SALIDA COMPLEMENTARIA, Y BANCOS [HD1,HD2] PARALELOS DE FILTRADO PARCIAL PASO BAJO. EN EL CONTESTO PRESENTE, UN FILTRO RELLENO A CEROS INDICA A UN FILTRO EL CUAL PUEDE ESTAR BASADO SOBRE UN FILTRO LP, QUE SE EXPANDE CON UN NUMERO DE COEFICIENTES DE FILTRADO DE VALOR CERO ENTRE CADA COEFICIENTE DEL FILTRO ORIGINAL. EL BANCO DE FILTRADO PARCIAL [HD1] CONECTADO A LA SALIDA NORMAL DEL FILTRO BASICO [H1(Z)] ESTA DESTINADO A FILTRO DE SALIDA DE AQUELLAS BANDAS DEL BANCO DE FILTRADO LAS CUALES SON BANDAS DE PASO PARA EL FILTRO BASICO, DE MODO QUE SOLO UNA DE LAS BANDAS DEL BANCO DE FILTRADO SE ENCUENTRA SOBRE CADA SEÑAL DE SALIDA DEL CITADO BANCO [HD1] UNO DE FILTRADO PARCIAL. EL OTRO BANCO [HD2] DE FILTRADO PARCIAL CONECTADO A LA SALIDA COMPLEMENTARIA DEL FILTRO BASICO [H1(Z)] SE DESTINA A FILTRAR LA SALIDA DE AQUELLAS BANDAS DEL BANCO FILTRADOR QUE SON BANDAS DE PASO PARA LA SALIDA COMPLEMENTARIA DEL FILTRO BASICO, DE MODO QUE SOLO UNA BANDA DEL BANCO FILTRADOR SE ENCUENTRA SOBRE CADA SEÑAL DE SALIDA DEL SEGUNDO BANCO [HD2] DE FILTRADO PARCIAL.
