Abstract
DISPOSITIVO PARA GENERAR SECUENCIAS PSEUDO-ALEATORIAS DE DIGITOS BINARIOS, EL CUAL ESTA ASOCIADO CON UN APARATO LOGICO AL QUE SE ACOPLAN CUATRO LINEAS PARA TRANSMITIR LOS DATOS LOGICOS QUE TIENEN UNA FRECUENCIA QUE ES CUATRO VECES LA MENCIONADA FRECUENCIA Y QUE RESPONDE AL CONTROL DE DICHO DISPOSITIVO. CONSTA DE SIETE BLOQUES SECUENCIALES SEMEJANTES (A1, A2, A3, A4, A5, A6, A7), EN CADA UNO DE LOS CUALES ESTA INDICADO RESPECTIVAMENTE LA ENTRADA (D), LA SALIDA (Q), LA ENTRADA DE RELOJ (CK) Y LA ENTRADA DE PRESELECCION (PR); DE CUATRO CIRCUITOS LOGICOS "AND" DE DOS ENTRADAS; DE CUATRO CIRCUITOS LOGICOS "EXCLUSIVOS-OR", CUYAS PRIMERAS ENTRADAS SE ACOPLAN CORRESPONDIENTEMENTE A LAS SALIDAS DE LOS CIRCUITOS LOGICOS "AND"; Y DE UN MULTIPLEXOR EQUIPADO CON CUATRO ENTRADAS A LAS QUE SE ACOPLAN LAS SALIDAS DE LOS CIRCUITOS "EXCLUSIVOS-OR".
