Figure 1 The XOR logic element and its analog using discrete elements.. The second variant of the 2XOR element is shown in Figure 2.Transistors Q1 and Q2, as well as resistor R2, serve as the 2AND ...

As previously mentioned by WStephenWoodward, XOR is associative so we can rewrite A xor B xor C as (A xor B) xor C . This represents two 2-input XOR gates with A and B into one and the output of that ...

[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 is ...

After clearing the XOR circuit, the next step is to create an 'arithmetics' circuit. The first arithmetic circuit can perform binary addition of one digit 'Half Adder ( half adder is).' ...

The circuit on the right in Figure 2 is used for the XOR circuit. If either A or B is low, then the inverting input is clamped to 0.7V, and the other high input generates a high output.
