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 ...

I wonder if this is the right forum to ask this question in.Anyways, today in class we went over logic gates: AND, OR, XOR, and NOT. Now, I can remember AND and NOT but not OR and XOR. AND is just ...

[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 reference frequency in this circuit drives the input of an exclusive-OR gate (XOR gate U2) as well as the input to a delay circuit. Consisting of R1, C1, and comparator U1, the delay circuit ...

There usually follows a demonstration of simple AND, OR, and XOR gates made from NAND gates, and maybe a flip-flop or two.

A simple and universal DNA-based platform is developed to implement the required two logic gates of a half adder (or a half subtractor) in parallel triggered by the same set of inputs. The ...
