- 2. EncoderENCODER- a digitalcircuit that produces a binary output code depending on which of its inputs are activated.
- 3. DecoderDECODER- a digitalcircuit that converts an input binary code into a single numeric output.

- 20. TESTANSWER THE FOLLOWINGQUESTIONS WITH ONE OR MORE OF THESE WORDS: MUX, DEMUX, ENCODER, DECODER.A. Has more inputs than outputs.ENCODER, MUXB. Uses select inputs.MUX, DEMUXC. Can be used in parallel-to-serial conversion.MUXD. Produces a binary code at its output.ENCODER
- 21. E. Only oneof its outputs is activated at one time.DEMUX, DECODERF. Used to route input signals to one of several outputs.MUXG. Used to generate arbitrary logic functions. MUX, DEMUXH. 3 line-to-8 line or binary to octal.DECODERMUX.I. Data Selectors are also
