The versatile phase-locked loop (PLL) allows multiplication of a reference frequency with an operating frequency that ranges from “DC to daylight.” A PLL is overkill for some applications, however, ...

Digital electronics rely on logic gates to perform operations. While modern integrated circuits (ICs) contain millions or billions of transistors packed into a small chip, understanding the ...

Logic Gates are among the important components of a circuit. All the logical operations required to perform a particular task in an electronic circuit are carried by these logic gates. If you are an ...

Drag and drop gates onto the workspace for easy circuit building. Click input/output nodes to draw and connect wires between gates. Supports multiple logic gates like AND, OR, NOT, NAND, NOR, XOR, and ...

An engineer has assembled the most complex logic circuit yet assembled in a single bacterium. The logic circuit, in which genes and the molecules that turn the genes on or off function as logic gates, ...

A flip-flop in digital electronics is formally defined as "A bistable device with synchronous inputs that changes state only at specified transitions of a clock signal" (IEEE Standard 91/1984) In ...

Here is a very nice project that [Znaxque] finished a few months ago: a simple nixie clock made with logic gates only. In this build, the mains 50Hz is used as a time base instead of a 32KHz crystal ...

One of the hardest things about studying electricity, and by extension electronics, is that you generally can’t touch or see anything directly, and if you can you’re generally having a pretty bad day.

Living cells make decisions based on information processing genetic programmes. Many of these programmes execute digital functions 1,2,3,4,5,6,7,8. The capability to build synthetic digital systems in ...
