▷ SOLUCIÓN LECCIÓN SISTEMAS DIGITALES 1, 2do Parcial (2021 PAE) C5

La siguiente tabla característica describe el funcionamiento de un flip-flop “XY” (FF-XY). Para realizar una conversión exitosa de un flip-flop “JK” (FF-JK) a un FF-XY, determinar cuáles de las siguientes expresiones booleanas describen correctamente el funcionamiento de las señales “J” y “K”:
  • a) j <= ‘0’ when (x&y = “11”) else ‘1’;
  • b) j <= ‘0’ when (x&y = “10”) else ‘1’;
  • c) j <= ‘0’ when (x&y = “01”) else ‘1’;
  • d) j <= ‘0’ when (x&y = “00”) else ‘1’;
  • e) k <= ‘0’ when (x&y = “11”) else ‘1’;
  • f) k <= ‘0’ when (x&y = “10”) else ‘1’;
  • g) k <= ‘0’ when (x&y = “01”) else ‘1’;
  • h) k <= ‘0’ when (x&y = “00”) else ‘1’;

Resolución:
j <= not(x) or not (y); entonces, j <= ‘0’ when (x&y = “11”) else ‘1’;
k <= x or y; entonces, k <= ‘0’ when (x&y = “00”) else ‘1’;
