Digital modulation

digital modulation Analog vs digital modulation modulation is the process of modifying one signal based on another, and it is used mostly in the transmission of data from one point to another.

A primer on digital modulation by bertrand zauhar, ve2zaz august 2013. Today vast amounts of information are communicated using radio communications systems both analogue radio communications systems, and digital or data radio communications links are used however one of the fundamental aspects of any radio communications transmission system is modulation, or the way. Digital modulation is the process of converting a digital bistream into an analog signal suitable for rf transmission modulation index back to top. This lecture will examine how we can communicate information in digital form by modulation of a carrier waveform although this process is referred to as digital modulation (dm) it generally involves some form of am and/or fm or pm.
