Question

b) ............having n inputs and one output
i) Encoder ii) IC 555 iii) Multiplexer iv) DE multiplexer​

Answer 1

Answer:

encoder

Explanation:

the above ans is true

Answer 2

Answer:

multiplexer

Explaination:

It is a combinational circuit which have many data inputs and single output depending on control or select inputs.​ For N input lines, log n (base2) selection lines, or we can say that for 2n input lines, n selection lines are required. Multiplexers are also known as “Data n selector, parallel to serial convertor, many to one circuit, universal logic circuit​”.
