Abstract

CIRCUITO SEUDOALEATORIZADOR DESEUDOALEATORIZADOR DIGITAL CAPAZ DE EVITAR SECUENCIAS DE PERIODO UNIDAD. UN SEUDOALEATORIZADOR CONSTA DE UNA SERIE DE LAZOS DE REALIMENTACION SERIE QUE ESTAN FORMADOS POR UNAS UNIDADES DE RETARDO (H) Y POR UNAS CELULAS (K) QUE REPRESENTAN LA SUMA DE MODULO 2, UNA LOGICA DE CONTROL ADICIONAL ASOCIADA (LCA), Y UN SEUDOALEATORIZADOR BASICO. LOS MISMOS ELEMENTOS DISPONE EL DESEUDOALEATORIZADOR, PERO CON UNA DISPOSICION CAMBIADA. EL CIRCUITO PERMITE REDUCIR COMO MININO A LA MITAD LA CIRCUITERIA DE LA LOGICA DE CONTROL ADICIONAL, YA QUE EN ALGUNAS CELULAS DE RETARDO (H) APARECEN UNOS PUNTOS (A), EN LOS QUE EL ESTADO BINARIO SIEMPRE ES UN CERO, DE ESTA FORMA ES, EN ESTOS PUNTOS (A), DONDE ACTUARA LA LOGICA DE CONTROL, NECESITANDOSE UNICAMENTE UNAS CELULAS CAPACES DE DETECTAR EL CERO EN ELLAS.
