A Digital to Analog Converter (DAC) is an electronic device that transforms digital signals, which are composed of binary numbers (0s and 1s), into analog signals. These analog signals can be used to drive speakers, televisions, and other devices that require continuous waveforms to produce sound or images. DACs are essential in various applications, including audio equipment, telecommunications, and video devices. They enable digital media, such as music files or streaming content, to be converted into a format that can be perceived by human senses, allowing us to enjoy high-quality audio and visual experiences.
