As an example, let’s consider the AND gate (the others are OR, NOT, NAND, NOR, XOR and XNOR ... done an excellent job of explaining relay-based logic. The image below show his implementation ...

Here’s a really fascinating circuit that implements a combination lock using relays and logic gates ... The other chips provide XOR, OR, and AND gates respectively. The relays were chosen ...

but we can show how an XOR is created from our three basic boolean gates. We know we have two inputs again -- A and B -- and one output. Let's start with an OR gate, since the logic table looks ...

So, before we leap into the more complex problem without XOR gates, let's first consider the XOR-based possibilities. And just to remind those who don't play with logic gates every day, the truth ...

A technical paper titled “The RGATE: an 8-in-1 Polymorphic Logic Gate Built from Reconfigurable Field Effect ... we show an experimental demonstration of NOT, NAND, NOR, XOR and XNOR Boolean functions ...

The family is available in nine different logic gates: NAND and AND, NOR, OR and XOR, and several buffer functions. To increase application flexibility and further boost performance, the company ...
