 *LOGIC GATES ; Logic gates  are the basic building blocks of any digital system. It is an electronic circuit having one or more than one input and only one output. The relationship between the input and the output is based on a   certain logic . Based on this, logic gates are named as AND gate, OR gate, NOT gate etc. *ANT GATE A circuit which performs an AND operation is shown in figure. It has n input (n >= 2) and one output. Logic diagram Truth Table OR GATE A circuit which performs an OR operation is shown in figure. It has n input (n >= 2) and one output. Logic diagram Truth Table *NOT GATE NOT gate is also known as  Inverter . It has one input A and one output Y. Logic diagram Truth Table *NAND GATE A NOT-AND operation is known as NAND operation. It has n input (n >= 2) and one output. Logic diagram Truth Table ✓NOR GATE A NOT-OR operation is known as NOR operation. It has n input (n >= 2) and one output. Logic diagram Truth Table ✓XORGate XOR or Ex-OR gate is a speci

Binary arithmetic Introduction An important part of the use of logic circuits is for computing various mathematical operations such as addition, multiplication, trigonometric operations, etc. We must therefore have a way of representing numbers as binary data. Nonnegative integers The easiest numbers to represent are the nonnegative integers. To see how this can be done, recall how we represent number in the decimal system. A number such as  2034  is interpreted as: 2*10 3 + 0*10 2 + 3*10 1 + 4*10 0 But there is nothing special with the base  10 , so we can just as well use base  2 . In base  2 , each digit value is either  0  or  1 , which we can represent for instance by  false  and  true , respectively. In fact, we have already hinted at this possibility, since we usually write  0 , and  1  instead of  false  and  true . All the normal algorithms for decimal arithmetic have versions for binary arithmetic, except that they are usually simpler. For adding two numbers, it suffices

NUMBER SYSTEM CONVERSION -  October 07, 2020 NUMBER BASE CONVERSION                     In our previous section, we learned different types of number systems such as binary, decimal, octal, and hexadecimal. In this part of the tutorial, we will learn how we can change a number from one number system to another number system. As, we have four types of number systems so each one can be converted into the remaining three systems. There are the following conversions possible in Number System Binary to other Number Systems. Decimal to other Number Systems. Octal to other Number Systems. Hexadecimal to other Number Systems.                                                                                                                                                                                                                                     1.BINARY NUMBER SYSTEM CONVERSION  Number System with base value 2 is termed as Binary number system. It uses 2 digits i.e. 0 and 1 for the creati

Number system October 06, 2020 NUMBER SYSTEM   When we type some letters or words, the computer translates them in numbers as computers can understand only numbers. A computer can understand the positional number system where there are only a few symbols called digits and these symbols represent different values depending on the position they occupy in the number. The value of each digit in a number can be determined using − The digit The position of the digit in the number The base of the number system (where the base is defined as the total number of digits available in the number system) DIFFERENT TYPE OF NUMBER SYSTEM The classification of numbers systems on the basis of base can be understood from the below diagram. Number system Base Used digits Binary 2 0,1 Octal 8 0,1,2,3,4,5,6,7 Decimal 10 0,1,2,3,4,5,6,7,8,9 Hexadecimal 16 0,1,2,3,4,5,6,7,8,9, A,B,C,D,E,F      A link that describes the above, https://youtu.be/32Kwy3GWQWc                                       or
