Abstract

PARA CONMUTAR ENTRE SEÑALES DE FRECUENCIA MODULADA Y DE ALTA FRECUENCIA, ESTAS ULTIMAS DESCIENDEN EN SUS AMPLITUDES DURANTE LA CONMUTACION. DE ESTA FORMA SE CONSIGUE UNA REDUCCION IMPORTANTE DE RUIDOS MOLESTOS, QUE APARECEN EN LA RECEPCION DE EMISIONES DE ONDAS ULTRACORTAS EN EL GIRO DE FASES O EN SALTOS DE FASES. EL PROCEDIMIENTO SIRVE SOBRE TODO EN RELACION CON SISTEMAS DIVERSOS DE ANTENAS, EN LOS QUE LOS SALTOS DE FASES SON MUY FRECUENTES.
