Design a 2-to-4 decoder with Enable input. Use only NAND and NOT gates. The circuit should operate with complemented Enable input and with complemented outputs. That is, the decoder is enabled when E is equal to 0 (when E is equal to 1, the decoder is disabled regardless of the values of the two other inputs; when disabled, all outputs are HIGH). The selected output is equal to 0 (while all other outputs are equal to 1).
