Modern Digital Modulation
w/Jim Hedrick, WB2LKZ
Modern communications systems need to transmit more and more information, more and more quickly, and use less and less channel bandwidth. To meet this need engineers and scientists have been developing new modulation techniques. For this talk Jim would like to explore the fundamentals of modulation and their relationship to current modulation techniques.
