Analog signals are continuous electrical signals that vary in amplitude and frequency, representing real-world phenomena such as sound or light. Digital signals, on the other hand, are discrete signals that represent data in binary form, either as a high or low voltage. In technology, analog signals are converted into digital signals through a process called analog-to-digital conversion, allowing for easier storage, transmission, and manipulation of data. Digital signals are more resilient to noise and distortion compared to analog signals, making them more commonly used in modern technology. **
