6. A circuit which translates n input lines into an m-bit code word, where n <= 2^m is defined as a

  1. MUX
  2. DeMUX
  3. Encoder
  4. Decoder
  5. ROM

4 is WRONG. A decoder is defined as a circuit which converts an n-bit input codeword into m lines of output, where m is less than or equal to 2^n, which is just the opposite operation of an encoder.
