Abstract

DISPOSITIVO DE INTERPOLACION DE SEÑALES. DISPOSITIVO DE INTERPOLACION PARA LA OBTENCION DE VALORES INTERMEDIOS ENTRE DOS MUESTRAS CONSECUTIVAS DE UNA SEÑAL, ESPECIALMENTE APLICABLE EN DEMODULADORES Y SISTEMAS DE ADQUISICION DE DATOS A ALTA VELOCIDAD. COMPRENDE UNOS MEDIOS DE RETARDO (T) QUE RETARDAN N VECES LA SEÑAL DE ENTRADA (X0), OBTENIENDO N+1 MUESTRAS TOTALES (X0, X1, X2, X3); Y UNOS MEDIOS DE ALMACENAMIENTO DE DATOS (F0, F1, F2, F3) QUE RECIBEN CADA UNO UNA DE LAS N+1 MUESTRAS TOTALES (X0, X1, X2, X3) Y EL VALOR DE LA FRACCION DEL INTERVALO DE TIEMPO (MI) Y GENERAN N+1 SALIDAS (X0", X1", X2", X3''); UNOS MEDIOS DE SUMADO (SUM) QUE SUMAN LAS N+1 SALIDAS (X0", X1", X2", X3'') DE LOS DISPOSITIVOS DE ALMACENAMIENTO DE DATOS (F0, F1, F2, F3), Y GENERAN UN VALOR INTERPOLADO FINAL (X). CADA DISPOSITIVO DE ALMACENAMIENTO DE DATOS (F0, F1, F2, F3) CONTIENE UNA TABLA DE VALORES, DE FORMA QUE LOS VALORES DE SALIDA DE CADA UNO DE ELLOS (X0", X1", X2", X3'') SON FUNCION DE LOS VALORES DE ENTRADA QUETOME EN CADA CASO LA FRACCION DEL INTERVALO DE TIEMPO (MI) Y DEL VALOR DE SU CORRESPONDIENTE MUESTRA (X0, X1, X2, X3).
