2. Binary Codes - Part C

The chapter discusses various digital coding systems, including Unicode, ISO-10646, and error detection and correction codes such as parity codes, repetition codes, and the Hamming code. It thoroughly evaluates how these systems help in representing characters across multiple languages and ensuring data integrity during transmission. Key examples, including seven-segment displays, further illustrate these coding techniques.

Sections

  • 2.5

    Seven-Segment Display Code

    This section details seven-segment displays, their configurations, and the binary codes used to depict numbers and letters.

  • 2.6

    Error Detection And Correction Codes

    Error detection and correction codes are essential for ensuring reliable data transmission by identifying and correcting errors that occur during the communication process.

  • 2.6.1

    Parity Code

    The parity code incorporates an extra bit added to data strings for error detection.

  • 2.6.2

    Repetition Code

    The repetition code enhances data integrity through the redundant transmission of bits, allowing for detection and correction of single-bit errors.

  • 2.6.3

    Cyclic Redundancy Check Code

    Cyclic Redundancy Check (CRC) codes provide an effective way to detect errors in transmitted data with low redundancy.

  • 2.6.4

    Hamming Code

    The Hamming Code enhances error detection and correction capabilities by using redundant bits arrangement, enabling the identification and correction of single-bit errors.

  • 2.7

    Review Questions

    This section poses questions that test understanding of digital encoding and error detection concepts.
