Natural Binary Code: The First

The simplest binary coding is natural. Like the original binary number system, it represents numbers with bits. All place values in the string are powers of two, with the rightmost bit being 20=1.

The natural binary code for five is 0101 because:

0 * (2^3) = 0 1 * (2^2) = 4 0 * (2^1) = 0 1 * (2^0) = 1 0 + 4 + 0 + 1 = 5

Easy, right? This simple binary code may represent huge values with few bits, making it compact. Digital computers store and calculate using natural binary code.

However, the natural binary coding has drawbacks. Reading and understanding it at a glance can be difficult. Reading or creating the code is easy to make a mistake because the 0’s and 1’s appear alike. Another drawback is that noise or interference can flip a bit and change its meaning. Flipping the second bit changes 0101 (5) to 1101 (13) for example.

Gray and excess-3 binary codes were devised to fix these issues. The alternative codes are more error-tolerant and human-readable while efficiently encoding binary integers. The natural binary code is still used in digital computer and communication systems due to its simplicity and compactness.

That concludes a brief overview of the initial binary code. While more complicated codes have been devised, the natural binary code is still essential to digital technology.

Gray Code: Error-Reducing Binary Code

Gray code is a binary coding that lowers transmission mistakes. In contrast to natural binary codes, the Gray code ensures that two consecutive numbers differ by one bit. Even if a single bit error occurs during transmission, the received code will be the previous or next number, not something else.

A single bit mistake in natural binary can change the number. Even though they differ by one digit, binary numerals 01 and 11 are distinct. A bit mistake that transformed 01 to 11 during transmission would erase the meaning.

  • The Gray code solves this problem by assigning binary numbers in a precise fashion such only one bit changes between sequential numbers. Gray code’s first few numbers are:
  • 00
  • 01
  • 11
  • 10
  • 110
  • 111
  • 101
  • 100

One binary digit changes between any two consecutive numbers in the sequence. Even with a single bit error, the received number would be near to the intended value.

The Gray code reduces communications, analog-to-digital converter, and position encoder errors. Some applications employ Gray coding to describe moving parts, such camera apertures. If one bit is misread, the position will be off by one increment.

Although elegant in its error-reducing simplicity, the Gray code is less efficient than natural binary codes for mathematical operations due to its non-linear sequencing. Error resistance outweighs these shortcomings for its intended applications. Gray coding helps prevent errors when transmitting or receiving binary data.

Excess-3 Code: More Reliable Than Binary

The excess-3 binary encoding is more reliable than ordinary binary. It employs the same two numbers, 0 and 1, but weights them by location. This detects single-digit mistakes.

1101 is 1 x 8 + 1 x 4 + 0 x 2 + 1 x 1 = 13. Weights in excess-3 are 1, 3, 9, 27, etc. Over-3 1101 = 1 x 1 + 1 x 3 + 0 x 9 + 1 x 27 = 31.

  • See how a single digit miscalculation in the third position of 1101 in excess-3 (changing it to 1011) yields 40, a clearly wrong number? This built-in error detection lets excess-3 be used in computer memory and communication systems where data integrity is crucial.
  • Make a binary number excess-3:
  • Write the binary number. Example: 1101.
  • From 1, weight each digit position: 1, 3, 9, 27, 81, etc.
  • Multiply binary digit weights. 1×1, 1×3, 0x9, 1×27.
  • Add Step 3’s merchandise. 1 + 3 + 0 + 27 = 31.
  • Excess-3 code total. The binary number 1101 is 31 in excess-3.
  • Long division converts excess-3 to binary. For 31:
  • 31/one = 31 remainder 0. Note the 0.
  • 31/3 = 10 leftover 1. Record the 1.
  • One remaining from 10/9. 1. Record the 1.
  • 1/27 = 0 remaining 1. Record the 1.

From bottom to top: 0111. Thus 31 excess-3 = 0111 binary.

Despite its complexity, the built-in error detection of excess-3 code makes it beneficial for data-critical applications. For many digital systems, reliability gives piece of mind.

BCD: Binary-Encoded Decimal Hybrid

BCD, short for Binary-Coded Decimal, combines binary and decimal numbering systems. As its name implies, it converts decimals to binary.

A four-bit binary integer represents each decimal digit 0–9. 0 is 0000, 1 is 0001, 2 is 0010, and so on up to 9 is 1001. Each digit can be encoded separately in BCD to represent all decimal integers.

The BCD code is important for binary-decimal conversion. Numerous modern displays display decimal numbers yet connect with binary computers. The computer sends binary-encoded decimal values to the display using BCD. No further conversion circuitry is needed.

Many arithmetic logic units (ALUs) employ BCD for decimal math. A BCD-based ALU can directly use encoded decimal values, but a binary math ALU must translate to and from decimal. This accelerates decimal calculations.

The biggest drawback of BCD is its space inefficiency. Decimal values require more bits than binary since each digit takes four bits to encode. Usability typically outweighs space efficiency when interacting with decimal-based technologies.

Combining numbering systems as in the BCD code gives the best of both worlds. Encoding decimal digits into four-bit binary values allows efficient decimal computations and interaction in a binary world. BCD, though not compact, is used in many applications that require decimal and binary values.

Computers, Communications, and More Use Binary Codes

Binary codes are useful in computers, communication systems, and more.

Computers digital

Digital computer information must be represented by binary numbers. In essence, computers manipulate binary data streams. Your computer’s processor executes binary machine code, which commands it. Your files, photos, software, and media are saved as bits of binary data. Our beloved computers wouldn’t exist without binary.

Communication Systems

Cell phones, Wi-Fi, Bluetooth, and others use binary codes. Calls and texts are translated into binary code, sent to the recipient, and decoded into comprehensible information. Binary swiftly and accurately transfers massive volumes of data between electrical devices.

Detect and Fix Errors

Error checking methods in some sophisticated binary codes can detect and repair transmission or storage faults. The Hamming code adds parity bits to let the computer know if any bits in the codeword have been flipped, even if just one bit is changed. Modern communication systems depend on these error-detecting and error-correcting codes.

Binary codes affect many aspects of your life, whether you recognize it or not. Almost all modern technology, from life-saving medical gadgets to smartphones, manipulates binary data. Despite its simplicity, binary has enabled some of the most complicated and influential technologies in history. Stop and admire the binary code powering your computer or phone next time you use it.


After learning about some of the coolest binary codes, you may start investigating their uses. From computers and communications to error detection, these clever codes power our digital world. Binary codes may appear complicated, but this beginner’s guide has showed you their basics. You saw how a few basic principles can convert our numbers and letters into machine-readable language.
