Abstract

SE INDICA UN CIRCUITO DE VIA MODULADO EN FRECUENCIA, CON RECEPTORES (8) CON UNA ANCHURA DE BANDA ESTRECHA, YA QUE ESTE NO SE PERTURBA. PARA LOGRAR EN LA TENSION DE VIA MODULADA EN FRECUENCIA CUYA VARIACION DE FRECUENCIA SUPERA AMPLIAMENTE LA BANDA ESTRECHA DE LOS RECEPTORES, UNA BANDA ESTRECHA, SE UTILIZA FILTROS (7) PARA BANDAS REGULABLES Y QUE TIENE UNA FRECUENCIA DE CENTRADO SIMILAR A LA FRECUENCIA DE LOS EMISORES (2) DEL CIRCUITO DE LA VIA. LA SEÑAL DE SALIDA DE LOS MISMOS DEL CIRCUITO DE VIA SE CONDUCEN AL RECEPTOR DE VIA POR UNA CONEXION (9).
