Logic gates are in fact the building block of digital electronics; they are formed by the combination of transistors (either BJT or MOSFET) to realize some digital operations (like logical OR, AND, INVERT ). Every digital product, like computers, mobile, calculators even digital watches, contain logic gates. The use of logic gates in digital world can be understood better by the following example: the single bit full adder in digital electronics is a logic circuit which perform the logical addition of two single bit binary numbers (a,b,cin) a and b are the the two binary number of single digit (either 1 or 0) and cin is the carry input . say for example a,b,cin= 1,1,1 gave an logical sum output of 1 and a carry of 1 , a,b,cin= 110 gave sum= 0 and carry of 1. Now this adder can be formed by the combination of many gate like by using NAND gates only. or by using XOR , AND ,OR gates and so on. So, in a nutshell, the adder which is of great importance in your computer processor and also in many more applications is basically built from the logic gates.
why we called logic gates are basic gate means,with help of those basic gates we can built electronics devices which operates in different states.
And, or, xor, xnor, nand, nor, not
it can be used in buffers,rectifiers,logic gates.
A: They are not preferred one or the other .
logic gates r used in alarms.
AOI logic, which uses AND, OR,and INVERTER(NOT) gates NAND/NOR Logic, this uses only NAND or NOR gates respectively.
A NOT logic gate flips the logic signal from 1 to 0 or 0 to 1 :)
limitations of logic gates
types of optical logic gates
They convert the command given by us in the form of binary
AND logic gate is used to obtain the product of two digits. It is used in various combinational and sequential circuits.
All digital electronic circuits are composed of logic gates. Without logic gates there would be no digital electronics.
logic gates comes under semiconductor
because similry logic gates used on and off
And, OR and Not gates.
