DIGITAL ELECTRONICS

Digital electronics is?the study of electronic circuits that are used to process and control digital signals. In contrast to analog electronics, where information is represented by a continuously varying voltage, digital signals are represented by two discrete voltages or logic levels.

Examples of such devices are?computers, information appliances, digital cameras, digital televisions, flash memory, key USB memory, mobile phones, hard disks, and devices of computer memory. Digital signal processing works on analog signals after they have been converted to digital form.

Digital electronics are easier to design and manufacture than analog electronics, as they can be implemented using standard components such as transistors and gates. Digital electronics are more energy efficient than analog electronics, as they can perform the same operations using less power.

Advantages of Digital Electronics Over the Analog Electronics.?It is much easier and more convenient to store information in the digital system than in the analogue system. As the digital system has a noise-immunity feature, the data can be stored and later retrieved without destruction or degradation.
