Abstract
SE PROPORCIONA UN CIRCUITO DE PROCESO PARA PROCESAR UNA SERIE DE SEÑALES RECIBIDAS DE BOBINAS DE DETECCION (21, 23 Y 25), QUE FORMAN PARTE DE UN CODIFICADOR DE POSICION UTILIZADO PARA CODIFICAR LAS POSICIONES RELATIVAS DE DOS MIEMBROS QUE SE MUEVEN RELATIVAMENTE. EL CODIFICADOR DE POSICION PERMITE QUE CADA UNA DE LA SERIE DE SEÑALES PROCEDENTES DE LAS BOBINAS DE DETECCION VARIE SINUSOIDALMENTE CON LA POSICION RELATIVA DE LOS MIEMBROS PERO DESFASADAS EN RELACION MUTUA. EL APARATO DE PROCESO COMPRENDE MEZCLADORES (71, 73 Y 75) PARA MULTIPLICAR CADA UNA DE LAS SEÑALES RECIBIDAS CON UNA DE UNA SERIE CORRESPONDIENTE DE SEÑALES PERIODICAS DE VARIACION DEL TIEMPO, CADA UNA DE LAS CUALES TIENE EL MISMO PERIODO PREDETERMINADO Y UNA FASE PREDETERMINADA DIFERENTE, Y UN SUMADOR (93) PARA SUMAR LAS SEÑALES PROCEDENTES DE LOS MEZCLADORES. LA FASE DE LAS SEÑALES DE MEZCLA SE ELIGEN DE MANERA QUE LA SEÑAL DE SALIDA PROCEDENTE DEL SUMADOR CONTENGA UNA UNICA COMPONENTE PERIODICA QUE TENGA EL PERIODO PREESTABLECIDO CUYA FASE VARIA DE ACUERDO CON LA POSICION RELATIVA DE LOS DOS MIEMBROS.
