Abstract

RECEPTOR DE RADIO CON UN BUCLE DE ENCLAVAMIENTO DE FRECUENCIA. LA FIGURA REPRESENTA UN RECEPTOR DE FRECUENCIA MODULADA. COMPRENDE UN BUCLE DE ENCLAVAMIENTO DE FRECUENCIA (6 A 18) QUE TIENE UNA ENTRADA (3) DE SEÑAL, ACOMPLADA AL DISPOSITIVO DE ANTENA (100) A TRAVES DE UN AMPLIFICADOR (2). EL CIRCUITO DE CONTROL (19 A 27) ESTA ACOPLADO AL BUCLE DE ENCLAVAMIENTO DE FRECUENCIA Y A UNA ENTRADA (28) DE CONTROL DE UN CIRCUITO SILENCIADOR (29). EL CIRCUITO SILENCIADOR (29) TIENE UNA ENTRADA (33) ACOPLADA A UNA SALIDA (5) DEL BUCLE DE ENCLAVAMIENTO Y OTRA ENTRADA (34) ACOPLADA A UNA FUENTE DE RUIDO (30). EL BUQUE DE ENCLAVAMIENTO COMPRENDE: UN PASO (6) MEZCLADOR, UN FILTRO (7) DE PASO BAJO, UN CONVERTIDOR (18) DE FRECUENCIA A TENSION, UN AMPLIFICADOR LIMITADOR (15), UN CIRCUITO SUMADOR (16) Y UN OSCILADOR (17). SE OFRECE TAMBIEN UN RECEPTOR DE AMPLITUD MODULADA.
