A device which converts BCD to seven segment is called

 [A]. encoder [B]. decoder [C]. multiplexer [D]. none of these

Explanation:

Decoder converts binary/BCD to alphanumeric.

 Anu said: (Aug 13, 2015) Decoder is correct answer but how?

 Myvizhi said: (Sep 1, 2015) Decoder is one to many. Encoder is many to one.

 Prarthi said: (Jun 26, 2016) Decoder has n input and 2^n output.

 Ps Gurjar said: (Sep 30, 2016) It is called as decoder.

 Nivi said: (Nov 7, 2016) How decoder? Decoder in the sense it converts n input and 2^n output.

 Anusha said: (Feb 11, 2017) How it is possible?

 Manish Kumar Saini said: (Aug 13, 2017) Encoder :- encoder converts an active input signal into a coded output signal Decoder :- decoder converts the coded input signal into an active output signal. So, Decoder is correct answer

 Badhshah said: (Jan 6, 2018) The decoder has two possibilities. 1) For 'n' inputs it produces 2^n outputs and. 2) It converts encoded (binary) input into human understandable or as an active signal.

 Vijaya said: (Dec 5, 2018) Well said @Badhshah.

 Muthupandi said: (Dec 21, 2018) Why decoder is a BCD converter?

 Prasuna said: (May 22, 2020) Can anyone explain clearly, how decoder converts BCD to seven segment display?

 Sanj said: (Nov 14, 2020) What is seven-segment, Iis it means octal?
