In the paper, we present an analytical comparison for various modulation techniques that can be used in a digital communication system. Digital modulation offers more powerful security, information, quality communication, and great capacity. Therefore, digital modulation systems have a maximal and important role in their capacity to transfer bigger amounts of data than analogue ones. There are more types of digital modulation like multiple amplitudes, frequencies, and phase shift keys. The results examine the comparisons of modulation techniques and the benefits of each system to determine which would be the most suitable for a specific application. The paper also discusses the effectiveness of different bandwidth and power efficiency factors.
