Abstract
PARA DETECTAR SI UNA SEÑAL DE ENTRADA DE FM, TAL COMO LA DE SEÑAL DE VIDEO REPRODUCIDA, QUE INCLUYE COMPONENTES DE FRECUENCIA PARTICULAR QUE REPRESSENTAN INFROMACION PREDETERMINADA, FUE GRABADA EN UN PRIMER Y SEGUNDO MODO, CON LOS MODOS CON DIFERENTES BANDAS DE FRECUENCIA, UNA PRIMERA SEÑAL DE SALIDA SE PRODUCE CUANDO UN COMPONENTE DE FRECUENCIA PARTICULAR EN UNA DE LAS BANDAS DE FRECUENCIA SE DETECTA (23,25) Y UNA SEGUNDA SEÑAL DE SALIDA SE PRODUCE CUANDO UN COMPONENTE DE FRECUENCIA DIFERENTE, APROXIMADAMENTE IGUAL A LA DIFERENCIA ENTRE DOS VECES UNA FRECUENCIA PREFIJADA INCLUIDA EN OTRA DE LAS BANDAS DE FRECUENCIA Y LA FRECUENCIA PARTICULAR EN LA BANDA DE FRECUENCIA UNO, SE DETECTA (24,26). UNA SEÑAL INDICATIVA DE IDENTIFICACION DE MODO DE LA BANDA DE FRECUENCIA OCUPADA POR LA SEÑAL DE FM SE PRODUCE (27) EN RESPUESTA A LA PRIMERA Y SEGUNDA SEÑALES.
