Digital Systems Characteristics

Digital systems manipulate discrete elements of information, distinguishing them from analog systems, which handle continuous signals.
They are easier to design, providing a significant advantage over analog systems.

Number Systems

The binary number system is also known as base 2 and consists of only two digits: 0 and 1.
The octal number system is a base 8 number system utilizing digits from 0 to 7.
Decimal is a base 10 system, employing ten digits (0-9), while hexadecimal (base 16) includes digits 0-9 and letters A-F.

Boolean Algebra

A Karnaugh map (K-map) is used for simplifying Boolean expressions, making it easier to analyze and design digital circuits.
Closure in Boolean algebra refers to the ability to combine elements to form a new element within the same set.
Inverse describes a unique element that combines with another to produce the identity element.

Logic Gates Outputs

An AND gate produces a LOW output when one input is LOW and the other is HIGH.
The output of a NOR gate is LOW if at least one input is HIGH.
An EX-OR gate outputs LOW when both inputs are HIGH.
A NAND gate results in HIGH when both inputs are LOW.

Error Correction

Error correction codes enhance the reliability of digital systems by detecting and correcting errors during data transmission.

Two's Complement

The two's complement of the binary number 1010 is 0110.

Boolean Expressions

The evaluation of the expression A + 0 results in A, affirming the identity property in Boolean algebra.

Energy Consumption

Digital systems typically consume more energy than analog systems, highlighting a disadvantage despite their design advantages.

Conversion Methods

Binary to hexadecimal conversion involves grouping binary digits by fours for easier translation.
