The XNOR gate can be created using a special combination of AND, OR, and NOT gates. Let's denote the inputs as A and B. The AND gate in the circuit above ensures that the output is only high when the inputs are high. This accounts for the cases where an even number of inputs a...
The XOR operation of inputs A and B is A ⊕ B; therefore, the XNOR operation of those inputs will be (A + B) ̅. That means the output of the XOR gate is inverted in the XNOR gate. In the XOR gate operation, the output is only 1 when only one input is 1. The output is...
Furthermore we discovered symbol representations that performed better than the straight forward on/off rate coding signals for the XNOR and AND Boolean functions. We conclude that our approach is suitable for the exploration of signal encoding in networks of excitable droplets....
For this kind of systems, we assigned a specific task and concentrated on the characteristics of signals representing symbols. Given a Boolean function like Identity, OR, AND, NAND, XOR, XNOR or the half-adder as the target functionality, 2D networks composed of 10 x 10 droplets were ...
