Abstract

Procedimiento para la determinación de fluctuaciones de un cuerpo sin fin móvil, especialmente para hilos textiles, caracterizado porque un sector de determinada longitud de la señal (F'') se transforma en una secuencia de impulsos de señal (S'') que representa las puntas de la señal (F'') que sobrepasan un determinado valor de umbral (S) y porque la frecuencia de impulsos de señal (S'') se tantea sucesivamente con una sucesión de impulsos de referencia (Z'') de periodo (p) preseleccionado, cuya posición de fase se varía en pasos sucesivos de determinada longitud (dn), en lo que para cada paso se determina el número (T) de las coincidencias de impulsos individuales de la secuencia de impulsos de señal (S'') y de la sucesión de impulsos (Z'') para determinar números elevados (T) como indicio para fluctuaciones periódicas.
