For applications not requiring fast conversion,a single circuit that can performboth conversions proves adequate. Onesuch circuit (Figure 1 ) utilizes up/downcounters to obtain the desired results.

Most people get scared by the idea of binary codes, but it is really as simple as understanding how a light bulb works.

We sure wish we’d had a teacher like [Danko Bertović]. He built this beautiful circuit sculpture to teach his students how to count in binary and convert it to decimal and hexadecimal. If you ...

With binary circuits, however, we're stuck with just two possible values—one binary digit. To represent all the other numbers we want to use, we have to use multiple digital signals—multiple ...

Explains the principles of transistor switching circuits, highlighting their role in electronic computers. It contrasts transistors with vacuum tubes, emphasizing that transistors function as ...

The approach offers a much wider range of results than a binary circuit (10,000 versus 2), and it exploits the cell enzymes' inherent ratio awareness to do some of the hard work.
