Abstract

SE PRESENTA UN APARATO PAR LA SINTONIZACION ADAPTATIVA DE UNA SEÑAL PERIODICA RECIBIDA. EL APARATO EMPLEA PREFERIBLEMENTE TECNICAS DE PROCESAMIENTO DE SEÑAL DIGITALES PARA LA GENERACION ALGORITMICA DE UNA SEÑAL DE SALIDA ESTIMADA SINUSOIDAL, DETERMINA LA DIFERENCIA ENTRE LA SEÑAL DE SALIDA ESTIMADA Y LA SEÑAL RECIBIDA, Y GENERA UNA SEÑAL DE ERROR BASADA EN LA DIFERENCIA ENTRE LA SEÑAL DE SALIDA ESTIMADA Y LA SEÑAL RECIBIDA. EL SEÑAL DE ERROR SE APLICA PARA VARIAR AL MENOS UN FACTOR DE LA DETERMINACION ALGORITMICA DE LA SEÑAL DE SALIDA ESTIMADA DE FORMA APROPIADA PARA REDUCIR EL ERROR ENTRE LA SEÑAL DE SALIDA ESTIMADA Y LA SEÑAL RECIBIDA.
