Logic and Circuits, lab 15

1. Using truth tables, verify that !(a&&b) and (!a)||(!b) have the same values on the same input. (Expressions with the same values on the same input are said to be equivalent.)
   
   
   
   
   
   
   
   
   
   
   
   
   
   
2. Draw a circuit for !( (r&&p)||(r&&q)||(p&&q)).
