The following overview should give you enough of an understanding about the basics of RF modulation to select the appropriate hardware for your next project. Three of the most common digital ...

The advances over the last several decades in hardware and digital signal processing have made digital transceivers much cheaper, faster, and more power efficient than analog transceivers. More ...

This is accomplished by using the digital signal to modulate the carrier. The carrier is modulated by using amplitude, phase, frequency modulation, or frequency hopping, or a combination of these.

Varying the voltage of a carrier or a direct current in order to transmit analog or digital data. Amplitude modulation (AM) is the oldest method of transmitting human voice electronically.

probability, random variables, and random processes, and introduces students to key concepts in digital information sources, analog-to-digital conversion, digital modulation, power spectra, ...
