Abstract

DISPOSITIVO LOGICO DEMODULADOR PARA SEÑALES MANIPULADAS POR DESPLAZAMIENTO DE FRECUENCIA (FSK) SOBRE UNA PORTADORA DE RADIOFRECUENCIA EN RECEPTORES DE RADIO DE CONVERSION DIRECTA. COMPRENDE DOS FLIPS-FLOPS, DE TIPO D TEMPORIZADOS, APLICANDOSE SEÑAL DE BANDA BASE DIRECTA A LA ENTRADA DE RELOJ DE UN FLIP-FLOP E, INVERTIDA, A LA ENTRADA DE RELOJ DEL OTRO FLIP-FLOP. LA SEGUNDA SEÑAL DE BANDA BASE SE APLICA A LAS ENTRADAS D DE AMBOS FLIP-FLOPS. LA SALIDA DE AMBOS SE COMBINAN ALGEBRAICAMENTE PARA PROPORCIONAR UNA SEÑAL DE SALIDA DEL DEMODULADOR DEL RECEPTOR. LAS SALIDAS DE LOS FLIP-FLOPS SE ELOGEN DE FORMA QUE PARA UN VALOR DE FSK DADO SIEMPRE TENGAN EL MISMO VALOR LOGICO. OTRAS DISPOSICIONES CONECTAN DE DIVERSAS MANERAS LAS SEÑALES DE BANDA-BASE Y LAS ENTRADAS EN LOS FLIP-FLOPS.
