2. Design a digital circuit, using a decoder, only Nor gates, a
7-segment display, and D Flip Flops, that repeatedly outputs the
sequences of characters ‘P’, ‘E’, ‘A’, ‘L’ if x=0 and ‘L’, ‘E’,
‘A’, ‘P’ if x=1 .
a. Create NAND gate using only transistors.b. Using the circuit block Create NAND gate using only
transistors , attach additional components to the circuit to have
