Analog signals reproduce real-world data, while digital signals convert this data into binary form. Interference can distort analog signals, making them unclear. Digital signals, however, remain clear despite interference because they only need to distinguish between ones and zeros.Analog signals reproduce real-world data, while digital signals convert this data into binary form.
