Like [Brad], we’ve seen a number of PCB rulers out there. [Brad] was looking to take the idea and run with it. His DigiRule is a ruler with a logic gate simulator. What he built is a mash-up … ...

1] Logic Friday LogicFriday is a free logic gate simulator software that comes with great features. In this software, you can create Truth Tables, Logic Equations, and Logic Gate Diagrams.

Truth table for an ‘AND’ gate: A ‘1’ in a truth table represents where the input or output is ‘high’, eg where a switch is pressed or a lamp is lit.

OR gate In an OR gate, at least one input must be 1 for the output to be 1. This can be seen in the truth table for the OR gate. If input A OR input B is true, then output (Q) will be true.

However, there are solutions requiring only two voltage levels; for example, consider Fig 9 . 9. NMOS and PMOS logic gates using common voltage level. As was noted above, the only real requirements ...
