  • 1. Encoder and Decoder
    Encoding, Decoding
  • 2. Encoder
    ENCODER- a digital circuit that produces a binary output code depending on which of its inputs are activated.
  • 3. Decoder
    DECODER- a digital circuit that converts an input binary code into a single numeric output.
  • 4. ENCODERS AND DECODERS
    ONLY ONE INPUT ACTIVATED AT A TIME
    BINARY CODE INPUT
    ONLY ONE OUTPUT ACTIVATED AT A TIME
    BINARY CODE OUTPUT
  • 5. THE 8421 BCD CODE
    BCD stands for Binary-Coded Decimal.
    A BCD number is a four-bit binary group that represents one of the ten decimal digits 0 through 9.
    Example:
    Decimal number 4926 4 9 2 6

    • Electronic decoders are available in IC form.
    • 13. This decoder translates from BCD to decimal.
    • 14. Decimals are shown on an 7-segment LED display.
    • 15. This IC also drives the 7-segment LED display.
  • TEST
