Abstract
Los sistemas y métodos se proporcionan para la generación de una señal controlada numéricamente con compensación de fase mediante el uso de un algoritmo de punto fijo. En un ejemplo, un método incluye recibir, en un dispositivo del interior del pozo, parámetros que incluyen una frecuencia de entrada y un valor de compensación. El método incluye adicionalmente convertir, en función de los parámetros, la frecuencia de entrada a un valor de fase delta. El método también incluye calcular, con el dispositivo del interior del pozo, un error de acumulación para una señal digital. En respuesta a determinar que el error de acumulación es mayor que o igual al valor de compensación, el método elimina el error de acumulación de la señal digital para generar una señal de salida.
