Abstract

Un receptor (603) realiza la recepción de una posición proporcionada por un primer valor que representa un primer parámetro de posición y un segundo valor que representa un segundo parámetro de posición. Un circuito de concordancia (605) determina si el segundo valor concuerda con un valor nominal. Si es así, un circuito de salida (609) genera datos de salida que incluyen datos que representan el primer valor en un campo de los datos de salida pero que no incluyen datos que representan el segundo valor en los datos de salida. De otra manera, el circuito de salida (609) incluye datos en el campo los cuales representan un valor de posición inválido para el primer parámetro de posición. Un receptor determina si los datos de un campo de datos representan un valor de posición válido para el primer parámetro de posición. Si es así, determina una posición en donde el primer valor es el valor de posición válido y el segundo valor es un valor nominal para el segundo parámetro de posición. De otra manera, determina el segundo valor a partir de un segundo campo de los datos de entrada.
