REVIEW
Review of Number Systems:
• Decimal to Binary & vice versa
• Hexadecimal to Binary & vice versa
• Octal to Binary & vice versa
eg: - Convert 6210 to Binary
- Convert 1111112 to Decimal
- Convert D716 to Binary
Alphanumeric Codes:
- Alphabets (A, B, C, …), Numbers (1,2,3,…), and
characters ( $, *,…) are represented by a unique binary
code.
REVIEW (cont.)
ASCII code:
- A character is represented by a 7 digit binary number
(X6…X0)
BCD code:
- Each decimal digit is represented by its' 4-bit binary
equivalent.
1’s and 2’s Complement:
- A  1's complement = A'
2’s complement = A' + 1
REVIEW (cont.)
eg. on 1’s and 2’s Complement :
710 = 01112 = X
-710 = 10012 = X’+ 1
 2's complement of any number represents its' negative
counterpart.
What is a microprocessor?
It is a digital system in single chip capable of performing
Arithmetic
What is a system?
Interconnection of components to perform specified
functions is referred to a system. If all the components are
digital in nature, it is called a digital system.
What is a combination circuit ?
The output is decided by the current input only.
What is a Sequential circuit ?
The output is decided by the current input and the
previous state of the output. A sequential circuit should
have a memory element.
