As a powerful material, DNA presents great advantages in the fabrication of molecular devices and higher-order logic circuits. Herein, by making use of the hybridization and displacement of DNA ...

An elementary electronic circuit in the arithmetic logic unit (ALU) of the CPU that adds one bit to another. The output of the half-adder is a result of 0 or 1 and a carry of 0 or 1. Additional ...

Switching algebra is easily visualized using switches since there are only two values: on and off, or true and false. In digital systems we represent these as 1 and 0, respectively. There are only two ...

Basically in digital system there are two type of circuit: combinational logic circuit and sequential logic circuit. When the authors talk about combinational circuit, this circuit is that circuit of ...

The screen of NandGame looks like this. We will install a NAND gate on the purple board and build a new circuit. The explanation of the circuit to be assembled is written on the left. The language can ...

Most of us can do simple math in our heads, but some people just can’t seem to add two numbers between 0 and 3 without using paper, like [Aliaksei Zholner] does with his fluidic adder circuit built ...
