What is MSK, Minimum Shift Keying Modulation

- overview, information and tutorial about the basics of what is minimum shift keying, MSK, a form of modulation used for radio communications applications, and in particular for digital forms of radio communications.
This phase modulation, PM tutorial is split into several pages:

[6] Different forms of QAM

Minimum shift keying, MSK, is a form of phase shift keying, PSK, that is used in a number of applications. A variant of MSK modulation, known as Gaussian filtered Minimum Shift Keying, GMSK, is used for a number of radio communications applications including being used in the GSM cellular telecommunications system. In addition to this MSK has advantages over other forms of PSK and as a result it is used in a number of radio communications systems.
