[IMSAI Guy] grabbed an obsolete XOR gate and tried a classic circuit to turn it into a frequency doubler. Of course, being an old part, it won’t work at very high frequencies, but the circuit… ...

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 ...

Integrated circuits contain multiple gates of a type, say NAND gates. If you have free gates in an IC using them for a circuit instead of adding another IC, like an XOR, saves money and board ...

'Nand Game' review to assemble a circuit from scratch using a NAND gate This article, originally posted in Japanese on 21:00 Dec 04, 2020, may contains some machine-translated parts.

First let's consider the NAND portion of this gate. When both the a and b inputs are presented with 1s, transistors Tr1 and Tr2 are turned OFF, transistors Tr3 and Tr4 are turned ON, and the internal ...

NAND gates are significant because any Boolean function (AND, OR, NOT, XOR, XNOR), which play a basic role in the design of computer chips, can be implemented by using a combination of NAND gates.
