There are several different types of binary codes used in digital electronics.Different binary codes are used for different purposes depending on the nature of application. For example, ASCII code is used for a
Binary counter can also be used as a sequence generator, where it can generate sequences of binary codes. Binary counters can be used in error detection and correction applications. This is all about binary counters in digital electronics. In conclusion, the binary counter is a versatile device...

Decimal numbers are converted into binary numbers for digital processing applications. In addition to binary number system, octal and hexadecimal number systems are also used for digital processing. Apart from numeric data, digital signal processing requires analog data. Binary codes are used to ...
The gray code belongs to a class of codes called minimum change codes, in which only one bit in the code changes when moving from one code to the next. The Gray code is non-weighted code, as the position of bit does not contain any weight. In digital Gray code has got a special pl...
In a digital computer these codes are based on the binary system, which uses two binary digits (1 and 0) so that one number (1) represents the presence of an electrical signal at a given time, and the other (0) denotes the absence of a signal. Binary signals then can represent both...
It’s as simple as that when you have all the decimal codes in front of you. A is equal to 1, B to 2, and so on until you hit Z at 26. Each letter is eight digits in binary When you aredealing with longer binary sequences, remember to separate each string by eight digits (bi...
The 4221 BCD and 5421 BCD are other weighted BCD codes shown in table. The numbers 4, 2, 2, 1 in 4221 BCD and 5, 4, 2 and 1 in 5421 BCD represent weights of the relevant bits. Now let us consider some examples, where we convert the given decimal numbers to BCD. ...
Furthermore, 33 non-printing control codes originating with Teletype machines were included in the original ASCII specification; most of these are now obsolete, although some are still commonly used, such as carriage return, line feed and tab codes. For example, binary 1101001= hexadecimal 69 (i...
How QR codes work, and what makes them dangerous: A computer scientist explains Among the many changes brought about by the pandemic is the widespread use of QR codes, graphical representations of digital data that can be printed and later scanned by a smartphone or other device. ...
