What is the difference between Analog and Digital Modulation?

The main difference between digital and analog is the fact that analog waves are smooth and continuous, while digital waves are usually stepping and a bit discrete. If you would like to know the difference between these two types of technologies, analog is known to be available first before digital. The analog wave will usually be taken in its original form.

The digital wave is known to be an interval that can be stored and transported into numbers that can be stored in a device. This explains why digital photos can be stored in smartphones, while analog devices will not have this option available. Some people say that analog is still more accurate than digital, but digital has made things more convenient.

There are many correct answers to this question. First, one must understand the term modulation. Modulation refers to the process of transmitting different frequencies using only one frequency. This process is most used in radio stations and is how many listeners are able to hear the same radio broadcast. With an analog modulation, signal is able to take up any value in a possible range.

There are three types of analog modulation, which include amplitude modulation (AM), frequency modulation (FM), and phase modulation (PM). Digital modulation differs because it can only take up one specific set of values. Types of digital modulations include amplitude shift keying and frequency shift keying.
