Abstract

UN CIRCUITO RECEPTOR CON OSCILADOR DE SINTONIA.COMPRENDE UN BUCLE EN EL QUE LA FRECUENCIA DEL OSCILADOR ESTA CONTROLADA POR LA SEN/AL UTIL, SIENDO NEGATIVA Y MAYOR QUE LA UNIDAD LA GANANCIA DE BUCLE EN EL MARGEN DE SINTONIZACION UTIL. ESTA PREVISTO UN ATENUADOR, EL CUAL ESTA CONTROLADO POR UN CIRCUITO DE CONTROL DE TAL MODO QUE A MAYORES DESVIACIONES DE LA FRECUENCIA INTERMEDIA OPERATIVA EN EL BUCLE A PARTIR DE UN VALOR OBJETIVO, SE REDUCE LA GANANCIA DE BUCLE.
