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.

This course is typically a live one hour online event but the recording can be made available on demand and online to support students requiring a more convenient viewing time. For on demand students, simply register online or by contacting the office and you will receive the login details for 30 day access to the recording..

This course is intended for registered individual students only. Please contact us for group rates at or 650-949-3300. Recording, copying, or re-transmission of classroom material is prohibited.

Learning objectives

Upon completing the course you will be able to:

  • 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

Target Audience

Engineers and technicians looking for an overview of basic digital modulation concepts.
