Difference of Analog and Digital
Analog Signal refers to a continuous data signal (Continuouse Data) with a constant signal size. There is a gradual change in signal size. It looks like a continuous curve. By transmitting an analog signal, it will be disturbed to be easily misinterpreted. For example, a signal in a telephone line digital signal (Digital Signal) refers to a signal related to discrete data (Discrete Data) of a certain size. This size may jump between two values, the highest signal and the lowest signal.
