A universal passive logic element of positive and negative logic, made on just one transistor, is proposed. The logic element has at least two inputs, as well as three outputs: an OR, an XOR, and an ...

The optoelectronic logic element AND, OR and XOR is considered, the output signal of which can be inverted when the input control signal is applied, thereby converting the logic element into NAND, NOR ...

Universal remotes are extremely convenient if they work correctly. But setting them up can be quite a hassle: often, you need to browse through long lists of TV models, key in the codes on the remote ...
