Background Information :
Logic provide atomic number 18 the simplest component of all logic circuit. So, to understand the
ready reckoner logic, you should understand and master the logic operators (gates). A
gate is a digital electronic circuit having only one fruit exactly one or more stimuluss. The
output or a signal will appear at the output of the gate only for certain infix-signal
combinations.
There are many types of logic gates; such as AND, OR and NOT, which are usually
called the terzetto raw material gates. other(a) popular gates are the NAND and the NOR gates;
which are simply combinations of an AND or an OR gate with a NOT gate inserted
just before the output signal.



Other gates include the XOR Exclusive-OR and the
XNOR Exclusive NOR gates.
In a digital system there are only few basic operations performed. These basic
operations are:
AND GATE
The AND gate performs logical multiplication. The output will be high only when all the
inputs are high. For a two input AND gate, the possible number of input combination is
four.
Mathematically, AND gate operation can be explicit as:

Y= A.B.C………N. Where A, B, C………, N are input variables and Y is an output
variable.
7408 is the digital IC in TTL and contains four AND.

OR GATE
The OR gate performs logical addition. Its output goes high if any of its inputs or both its
inputs is high. Mathematically, it can be expressed as:
Y=A+B+C+……..+N. Where A, B,...If you want to germinate a full essay, order it on our website: Orderessay
