Digital Modulation Webinar

This seminar covers the basics of analog and digital modulation, including sampling and pulsed signals. The fundamental digital modulation formats such as BPSK, QPSK, and QAM are described. Continuous-phase formats (MSK, FSK) are covered as well.
Learning Objectives:
  • identify the benefits of digital vs. analog modulation
  • identify the symptoms of aliasing caused by under-sampling a signal
  • apply pulse theory to the understanding of frequency and time domain interaction
  • identify basic digital modulation formats (BPSK, QPSK, etc.)
  • understand tradeoffs between data rate and noise immunity
