Join us at Pacific noon on November 11 (Wednesday) to participate



The word "revolution" is much less used than it might be, especially in the field of electronics. However, this is understandable-social changes caused by the "transistor revolution" or "PC revolution" or more recently, the "AI revolution" has undergone changes, which are usually beneficial and sometimes diseased. However, the common thinking is that once these revolutions occur, there will be no such thing again.

This is the case with software-defined radio (SDR) and digital signal processing (DSP). These two related fields don't seem to be as revolutionary as some other electronic revolutions, but when you think about it, they did change the world of radio communications. SDR means that complex radio transmitters and receivers no longer have to be strictly implemented in hardware as a collection of filters, mixers, detectors, and amplifiers; instead, they can be reduced to a series of algorithms running on a computer.

The collaboration of SDR and DSP has led to tremendous changes in the RF field. It was almost an afterthought that a powerful high-bandwidth radio link has been built into the device. However, these concepts may be difficult to take root at least when you delve into the basics and really try to learn the working principles of SDR and DSP. Fortunately, Dr. Marc Lichtman, an adjunct professor at the University of Maryland, did write this book.

It is a wonderful introduction to SDR and DSP, for people who want to learn how to use SDR and DSP in actual systems. Dr. Lichtman will stop by Hack Chat to talk about his textbook, answer questions about how to best understand SDR and DSP, and discuss the next steps once the basics are conquered.
