Please create a breadboard using fritzer.

The gate ICs to be used for the logic diagrams must be those from F ig. 9 .1 which contntain the following NAND gates:

7400 two?input NAND

7404 inverter (one?input NAND)

7410 three?input NAND

7420 four?input NAND

If an input to a NAND gate is not used, it should not be left open, but instead should be connected to another input that is used. For example, if the circuit needs an inverter and there is an extra two?input gate available in a 7400 IC, then both inputs of the gate are to be con nected together to form a single input for an inverter.
