Mixed-signal refers to electronic systems that combine both analog and digital signals. Analog signals are continuous and can represent a range of values, while digital signals are discrete and represent data in binary form. This combination allows for more versatile and efficient processing of information, making mixed-signal technology essential in various applications, such as telecommunications and audio processing. Devices that utilize mixed-signal technology include analog-to-digital converters (ADCs) and digital-to-analog converters (DACs). These components enable the conversion between analog signals, like sound waves, and digital signals, which can be processed by computers. Mixed-signal design is crucial in modern electronics, enhancing performance and functionality.
