This presentation contains the Encoder and Decoder details

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 8421 BCD coded number0100 10010010 0110

9. 10 line to 4 line Encoder

11. 4 line to 10 line Decoder

13. This decoder translates from BCD to decimal.

14. Decimals are shown on an 7-segment LED display.

20. TEST ANSWER THE FOLLOWING QUESTIONS WITH ONE OR MORE OF THESE WORDS: MUX, DEMUX, ENCODER, DECODER. A. Has more inputs than outputs. ENCODER, MUX B. Uses select inputs. MUX, DEMUX C. Can be used in parallel-to-serial conversion. MUX D. Produces a binary code at its output. ENCODER

21. E. Only one of its outputs is activated at one time. DEMUX, DECODER F. Used to route input signals to one of several outputs. MUX G. Used to generate arbitrary logic functions. MUX, DEMUX H. 3 line-to-8 line or binary to octal. DECODER MUX. I. Data Selectors are also
