What is the difference between analog and digital signals?
Analog signals are continuous waveforms that represent information through voltage or current levels that vary over time. Digital signals, on the other hand, involve discrete values to represent information, such as 0s and 1s. Analog signals can have an infinite number of possible values, while digital signals only have a finite number of discrete values.
Analog signals are more susceptible to noise and distortion, while digital signals are more resistant to noise interference. Analog signals are typically used in situations where precision and accuracy are important, such as in music or video recordings. Digital signals are commonly used in telecommunications, computer systems, and other digital devices because they can be easily processed and transmitted without losing information.
