What is adder ? & Types of adder..



What is adder ?
Ans:-  It is a combinational logic circuit used to add two or more than two either serially and parallely..
Q):-How many  types of adder are there?
Ans:- There are two types of adder.

  1. Half adder.
  2. Full adder.
1):- What is half adder?
Ans:- It is a type of adder which is responsible to add only two bit at a time.
In half adder there are two input terminal and two output terminal  one is sum and another one is carry .

What is demux (demultiplexer)? ( 2:4 ,3:8 & 4:16 demux )... Q) :- What is demultiplexer ? Ans:- It is a combinational logic circuit which is consist of single input and switches through many many output with the help of select line.. If ' n ' is the no of select line and ' N 'is the no of output line.                1:4 demux :- This demux consist of single data input line band switches through a four data output line with the help of select line. Let us consider ' I ' is input line.  S o & S 1 are select line and  Y 0, Y 1, Y 2, & Y 3 are output line. Truth table of 1:4 demux. Expression of 1:4 demux. Realisation of 1:4 demux.               1:8 demux This demux consist of single data input line and switches through a eight data output line with the help of select line. Let us consider I is the data input line and S 0, S 1 & S 2,  are select line and Y 0, Y 1, Y 2, Y 3, Y 4, Y 5, Y 6 & Y 7 are data outp
