Preparation before the lab* I. Examine the Preparation and Design sheet and write down the system truth table and then a Boolean expression for each of the LED segments (a...g) and the BELL signal as a function of the inputs L and B. II. Obtain NAND equivalent expressions for the Boolean obtained in I. III. Sketch your full NAND gate implementation on the lab Preparation and Design sheet, including pin number details.
