- describe the best definition you can find for XOR gate. Provide a simple application of the XOR gate.
- Until about 20 years ago, fixed logic gates were used to build a digital circuit. For a typical circuit, 20-30 ICs were used. Now we have programmable logic devices that can represent thousands of logic gates, all packed into a single package, for less than $10. So, why would we want to use the fixed logic gates?
