Abstract

AMPLIFICADOR CON RAPIDEZ DE RESPUESTA CONTROLADA UN AMPLIFICADOR CON RAPIDEZ DE RESPUESTA AJUSTABLE (26) EN EL ESTADIO DE ENTRADA DE UN CIRCUITO AMPLIFICADOR (10) QUE AYUDA A REDUCIR RADIACIONES ESPURIAS DE CANAL FUERA DE FRECUENCIA. EN LOS CASOS DONDE LAS SECUENCIAS DE PRUEBA SE INTRODUCEN EN UN CIRCUITO AMPLIFICADOR, LAS CUALES SE UTILIZAN PARA MEDIR LOS NIVELES DE ENTRADA MAXIMOS PERMISIBLES AL AMPLIFICADOR (34), LA INCLUSION DE UN AMPLIFICADOR CON BAJA RAPIDEZ DE RESPUESTA EN EL BUCLE DE ENTRADA EVITA LA PRODUCCION DE RADIACIONES ESPURIAS DE CANAL FUERA DE FRECUENCIA INCLUSO POR LA SECUENCIA DE PRUEBA DE ENTRADA. EL AMPLIFICADOR CON RAPIDEZ DE RESPUESTA AJUSTABLE (26) SE EJECUTA DE MODO QUE TENGA UNA RAPIDEZ DE RESPUESTA TOTAL, PROPORCIONANDO ASI UNA AMPLIFICACION DEL ANCHO DE BANDA TOTAL, DURANTE PERIODOS DE FUNCIONAMIENTO NORMAL DEL CIRCUITO
