Digital Techniques and Microprocessor Notes

 so here we completed binary subtraction using 1's and 2's complement method. in 1's complement method if carry is generated then add into the result but in 2's complement method if carry is generated then discard it or ignore the carry.

In this i explained binary arithmetic operations. Arithmetic operations includes binary addition, subtraction, multiplication and division etc  binary subtraction are performed by using complements. complements simplify subtraction operation in digital computer. 

here you will find conversion of number system. I am sure this will help you and very easy to learn.  Tricks to remember  1.when you convert decimal numbers into other number system then divide decimal number by radix of other number system.  E.g. converting decimal number into hex then divide decimal number by 16.  2. when you convert any number system into decimal then multiply converted  number digits by power of that converted number system.  E.g. convert octal into decimal then multiply octal digits by power of 8.  3. when you dealing with octal number system then make a group of 3 bits or represent number by group of 3 bits. E.g. 3=(011), 45=(100 101) etc. 4. when you dealing with hexadecimal number system then make a group of 4 bits or represent number by group of 4 bits. E.g. A=(1010), 3=(0011) etc.  here you will find a total chart of conversion of number system.

So, basically number systems are used in positional system of representing numbers, the numbers are important  because it represents base.  The decimal number system has radix 10 and we used decimal number system in daily life while dealing with money.likewise binary number system has radix 2 and it is mostly used in computer technology.  The octal has radix 8 and it is used as a shorthand for representing file permission on UNIX system and representation of UTF8 numbers. The hexadecimal number system has a radix 16 and it makes large binary numbers in just a few digits. 

Hello! In last post we had seen introduction of number system. now we are going to learn types of number systems.

Introduction:        Here I am talking about the term DIGITAL. It is for the most part connected with a PC. A PC performs procedure on tallying digits. Subsequently advanced is something which is countable. PCs acknowledges input store it, measure the information and produces the yield. Accordingly computerized frameworks are the electronic gadget or source which create stores and interaction the sign. From above PC is computerized framework sees just double language (0 or 1).       Some examples of digital systems are:      1)       Registers 2)       Flip-flops 3)       Counters 4)       Microprocessor 5)       Digital calculators etc. Number System:       ·          A number system defines a set of values used to represent a quantity. ·   ...
