4.1 Add an enable signal, en, to a 2-to-4 decoder. When en is '1', the decoder functions as usual. When en is '0', the decoder is disabled and output becomes "o000". Use the conditional signal assignment statement to derive this circuit. Draw the conceptual diagram 4.2 Repeat Problem 4.1, but use the selected signal assignment statement instead
