Introduction about ADC

In today's digital age, we encounter countless electronic devices and systems that rely on the conversion of analog signals into digital data. This process is made possible through a fundamental component known as an Analog-to-Digital Converter, or ADC. In this article, we will delve into the world of ADCs, understanding their basic principles, applications, advantages, challenges, and their vital role in modern technology.

Understanding ADC

What is an ADC?

An Analog-to-Digital Converter, or ADC, is an electronic device that plays a pivotal role in converting continuous analog signals into discrete digital values. This conversion allows electronic systems to process and manipulate the data efficiently. ADCs are essential in various applications, from audio and video recording to data acquisition systems.

How does it work?

ADCs operate by sampling the analog signal at discrete intervals and then quantizing these samples into digital values. The analog signal is continuous and can have an infinite number of values, whereas the digital signal consists of finite, discrete values. The process involves two crucial steps: sampling and quantization.
