A Digital-to-Analog Converter (DAC) is an electronic device that converts digital data, typically binary, into an analog signal, which can be used to drive audio devices, displays, or other analog systems. It is essential for interfacing digital systems with the real world, where signals are inherently analog.

An analog signal is a continuous signal that represents physical measurements and varies over time or space, capturing the full range of values within its limits. It is characterized by its ability to convey information through variations in amplitude, frequency, or phase, making it ideal for real-world data representation such as sound, light, and temperature.

Signals are functions that convey information about the behavior or attributes of some phenomenon, often represented as a function of time. They are fundamental in various fields such as communications, control systems, and signal processing, where they are analyzed and manipulated to extract or transmit information.
