It appears in a range of electronics applications and uses semiconductors.
The various electronic devices we use in everyday life include Computers Today, computers are using everywhere. At home, computers are used for playing games, watching movies, doing research, paying bills and reservation of tickets electronic circuits and devices railways and airlines.
At school, students use computers electronic circuits and devices complete their assignments. Mobile phones Mobile phones are used for variety of purposes such as for sending text messages, making voice calls, surfing internet, playing games, and listening songs. ATM ATM is an electronic telecommunication device particularly used for withdrawing money at any time from anywhere.
ATM stands for automated teller machine.
The customer can withdraw money up to electronic circuits and devices certain limit during anytime of the day or night. Digital circuits therefore can provide both logic and memory, enabling them to perform arbitrary computational functions.
Memory based on flip-flops is known as static random-access memory SRAM. Memory based on the storage of charge in a capacitor, dynamic random-access memory DRAM is also widely used.

- Electronic devices and circuit theory: An overview
The design process for digital circuits is fundamentally different from the process for analog circuits. Each logic gate regenerates the binary signal, so the designer need not electronic circuits and devices for distortion, gain control, offset voltages, and other concerns faced in an analog design.
As a consequence, extremely complex digital circuits, with billions of logic elements integrated on a single silicon chip, can be fabricated at low cost. Such digital integrated circuits are ubiquitous in modern electronic electronic circuits and devices, such as calculators, mobile phone handsets, and computers.
As digital circuits become more complex, issues of time delay, logic electronic circuits and devicespower dissipation, non-ideal switching, on-chip and inter-chip loading, and leakage currents, become limitations to the density, speed and performance.
These days analog circuitry may use digital or even microprocessor techniques to improve performance.
Electronic Devices and Circuits - What is electronics - Electronics definition
This type of circuit is usually called "mixed signal" rather than analog electronic circuits and devices digital.
Sometimes it may be difficult to differentiate between analog and digital circuits as they have elements of both linear and non-linear operation. An example is the comparator which takes in a continuous range of voltage electronic circuits and devices only outputs one of two levels as in a digital circuit.
Similarly, an overdriven transistor amplifier can take on the characteristics of a controlled switch having essentially two levels of output.
In fact, many digital circuits are actually implemented as variations of analog circuits similar to this example—after all, all aspects of the real physical world are essentially analog, so digital effects are only realized by constraining analog behavior.
Electronic circuits and devices electronics Digital circuits are electric circuits based on a number of discrete voltage levels. Digital circuits are the most common physical representation of Boolean algebraand are the basis of all digital computers.
To most engineers, the terms "digital circuit", "digital system" and "logic" are interchangeable in the context of digital circuits.
