Abstract

EL INVENTO CONCIERNE LOS BANCOS DE MEDIDA AUTOMATICO. LA MEDIDA AUTOMOTICA DE LA AMPLITUD DE UNA RAYA DE INTERMODULACION A LA SALIDA DE UN EMISOR TV ES DIFICIL DE REALIZAR PORQUE ESTA RAYA ESTA A MENUDO INCLUIDA EN UNA NEBULOSA DE RUIDO CONSTITUIDA POR LOS ESPECTROS DE LAS RAYAS DEBIDAS A LAS FRECUENCIAS MULTIPLES DE LA FRECUENCIA DE LINEA. NORMALMENTE LA MEDIDA ES REALIZADA HACIENDO UNA INTERPRETACION VISUAL. CUANDO LA MEDIDA ES REALIZADA AUTOMATICAMENTE, ESTA INTERPRETACION VISUAL NO ES POSIBLE. EL PROCESO SEGUN EL INVENTO UTILIZA EL CONOCIMIENTO A PRIORI DE LA EXISTENCIA DE UN PALIER EN EL VERTICE DA LA RAYA A MEDIR. CONSISTE EN : CONSIDERAR LAS MUESTRAS DE LA SEÑAL DE ESPECTRO SUMINISTRADAS PARA ANALIZAR, DURANTE UN INTERVALO DE TIEMPO CORRESPONDIENTE A LA DURACION DEL PALIER : CONSIDERAR UNA SERIE DE CORTES EN LA ESCALA DE LAS AMPLITUDES ; CONTAR EL NUMERO DE MUESTRAS QUE TIENEN UN VALOR PERTENECIENTE A UN CORTE DADO, SUCESIVAMENTE PARA CADA UNO DE LOS CORTES ; DETERMINAR QUE CORTE CORRESPONDE AL MAYOR NUMERO DE MUESTRAS, EL VALOR CORRESPONDIENTE A ESTE CORTE CONSTITUYENDO EL VALOR DE LA AMPLITUD DEL PALIER. APLICACION A LOS BANCOS DE MEDIDA AUTOMATICOS.
