Lesson 21: Digital Modulation
www.usna.eduLesson 21: Digital Modulation Objectives: (a) Quantitatively describe the relationship between a bit and a symbol, and the bit rate and the symbol rate (baud). (b) Describe how digital information is conveyed using various digital modulation techniques (ASK or OOK, FSK, PSK and QAM) and recognize their waveforms, and constellations.
