Digital Electronic & Microprocessors Flashcards
____ are those electronic systems that uses digital signal instead of an analog signal
Digital electronics
It comprises of various components each of which is used to perform a specific task
Digital circuit basics
It is used to allow the flow of current in a particular direction only
Diodes
It is basically a semiconductor device that has three terminals
Transistors
It is a passive component is used to opposite the flow of current in a circuit
Resistor
It consists of two conducting plates between which there is an insulator
Capacitor
It is used to store electric energy in a magnetic field
Inductors
Source of power
Battery
It is the most basic component of a digital circuit examples are basic gates universal gates and special gate
Logic gates
Another component of an an electric that can regulate the flow of electric current through the circuit
Switch
It is the central unit of a computer system
It performs arithmetic and logic operations which generally include adding subtracting transferring numbers from the area to another and comparing two numbers
Microprocessor
What are the three basic things that microprocessor do
It uses arithmetic or logic unit that can perform operations like adding subtracting and multiplication and division
it moves data from one by more location to another
it makes decisions and jump to a new set of instructions based on those decisions
Give some of the benefits of microprocessor
They don’t cost a lot
they are fast
theyconsumed little power
they are portable
they are reliable
they are versatile
How is robotics related to electronics
Robotics is a multidisciplinary area that combines electrical engineering mechanical engineering and computer science this area includes embedded programming control systems automated decision-making and power electronics
Importance of digital electronics and microprocessors in the society
It is very important in today’s life because if digital circuits compared to analog circuits are that signals represented digitally can be transmitted without the gradation due to noise microprocessors have transformed modern society they affect the way we work and play the way we travel and communicate the offer remarkable processing power at a very cheap cost
