Analogue and Digital Circuits: Characteristic Deconstruction, Scene Adaptation, and Selection Strategies

Abstract

As technology advances, circuit design remains a core topic among engineers, and how to select the correct circuits for specific electronic applications is well worth studying. Currently, research focuses on various application scenarios, including cost, design, high speed/frequency, and high accuracy/precision. For instance, consumer electronics prioritize low cost and miniaturization, while aerospace demands ultra-high reliability and anti-interference capability. This paper will first introduce the different functions of digital and analog electronics. Then, they will be analyzed in detail across different application scenarios, and real-life examples will be used to directly prove which type is more suitable for typical scenarios. Finally, it is found that different scenarios require different types of electronics. Sometimes, using only one type of electronics fails to work properly digital and analog electronics need to be combined to deliver the best performance. The conclusion is that circuit design and construction will be improved with the help of AI technology and new materials in the future.
