What is Encoder ? ( 4:2 Encoder )

What is  Encoder ? 

Ans-   It is a combination logic circuit which convert decoded information to binary signal.
                      OR
An encoder is a digital circuit that performs the inverse operation of a decoder.
                   



Note- A encoder has
input lines and "n" output lines.

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

Q):-  What is logic gate ? Ans:-   In   electronics , a  logic gate  is an idealized or physical device implementing a  Boolean function ; that is, it performs a  logical operation  on one or more  binary  inputs and produces a single binary output.      Q):-  How many types of logic gates are there ?  Ans:-  There are three types of logic gates.   1):-     Basic gate.   2):-.   Universal gate.   3):-     Arithmetic gate./ special gate.  1):- What is Basic gate ?    And:-   These gates gives idea about one of                the fundamental expression either                  addition of variable ,                   Multiplication of variable and                     Compliment of the variable.    How many types of Basic gate are there ?  And:-   There are three types of basic gate .  a):-   NOT gate / inverter .  b):-   AND gate .  C):-   OR gate .   a):- What is NOT gate ?  Ans:- Function of  NOR  gate is to reverse  the nature  of the
