The differences between analog and digital signals lie primarily in their representation of information. Analog signals are continuous, varying in amplitude and frequency, making them capable of capturing the nuances of sound and light. In contrast, digital signals represent data as discrete values, typically in binary form (0s and 1s), allowing for easier storage and processing. Digital signals are generally more resilient to noise, making them preferable in modern communication systems. The shift from analog to digital technology has revolutionized media, increasing efficiency and quality in various applications.
