Gate Universality

We know that the NAND gate is universal, so all other gates can be built using just NAND gates. We also mentioned that the NOR gate is universal, and can serve the same purpose. In this question we will look at NOR gates.

1. 
   

   Draw the AND operation as a circuit using a minimal number of NOR gates.

   
   


2. 
   

   Check your design in (a) by showing the full truth table for it.

   
   


3. 
   

   Draw the OR operation as a circuit using a minimal number of NOR gates.

   
   


4. 
   

   Check your design in (c) by showing the full truth table for it.

   
   


5. 
   

   Draw the NOT operation as a circuit using a minimal number of NOR gates.

   
   


6. 
   

   Check your design in (e) by showing the full truth table for it.
