What Is the Meaning of Digital Modulation?
Modulation alters properties of a waveform--called a carrier signal or wave. Digital modulation uses binary code to transfer a digital signal over an analog system such as a phone line, which is the case with a modem (modulator and demodula... Read More »

What are the goals for digital modulation?
Simply put, digital modulation is designed to maximize the amount of data we can put through a system per unit of time while maintaining the integrity of that data. Those are the two primary goals. Read More »

What is digital modulation?
In digital modulation, an analog carrier signal is modulated by a digital bit stream. Digital modulation methods can be considered as digital-to-analog conversion, and the corresponding demodulation or detection as analog-to-digital convers... Read More »
