Abstract

EN UN METODO PARA DETERMINAR UNA DIFERENCIA DE FASE ENTRE DOS SEÑALES ELECTRICAS CON FORMA DE SENO, EN LAS QUE LA DIFERENCIA DE FASE SE SABE QUE ES PEQUEÑA Y LAS SEÑALES ESTAN REPRESENTADAS DE FORMA COMPLEJA, EL VALOR CONJUGADO COMPLEJO DE UNA SEÑAL SE MULTIPLICA POR LA OTRA SEÑAL Y EL VALOR IMAGINARIO DEL RESULTADO SE UTILIZA COMO ESTIMACION DE LA DIFERENCIA DE FASE ENTRE LAS DOS SEÑALES. UN APARATO PARA EL MISMO PROPOSITO TIENE LINEAS DE SEÑAL PARA LAS DOS SEÑALES Y COMPRENDE MEDIOS QUE SON CAPACES DE MULTIPLICAR EL VALOR CONJUGADO COMPLEJO DE UNA DE LAS SEÑALES CON LA OTRA SEÑAL, Y QUE SON CAPACES DE REPRESENTAR EL VALOR IMAGINARIO DEL RESULTADO DE LA MULTIPLICACION SOBRE UNA SALIDA Y QUE LA UTILIZAN COMO ESTIMACION DE LA DIFERENCIA DE FASE ENTRE LAS DOS SEÑALES.
