Digital signal processing plays an important role in implementing transceiver functions after a signal has been digitized.
Besser Associates offers training courses on Digital Signal Processing. These courses develop the student's fundamental understanding of DSP theory. The practical aspects of signal processing techniques are stressed allowing DSP professionals to make their processing algorithms more efficient.
This video gives an example of a PID controller and explains its parts.
Charan Langton has a unique gift for creating tutorials on complex topics that are easy to read and understand. (She has also been known to attend a Besser Associates course from time to time!) She lists recommended books on her Complex to Real website.
Instructor Rick Lyons has written a new post on his blog at DSP Related discussing ways that you can use an FFT algorithm to compute the IFFT.
If you need to compute inverse fast Fourier transforms (inverse FFTs) but you only have forward FFT software (or forward FFT FPGA cores) available to you, below are four ways to solve your problem.
Instructor Rick Lyons has written a new post on his blog at DSPRelated.com:
I noticed the Wiki web site stated that a Goertzel filter:
"...is marginally stable and vulnerable to
numerical error accumulation when computed using
low-precision arithmetic and long input sequences."
Instructor Rick Lyons posted his list of free DSP books that are available for downloading in electronic format. The list is posted as an entry on his blog at DSPRelated.com.
Over forty books are listed and categorized by application.
Tim Wescott has joined Besser Associates with a new course on Applied Embedded Control Systems.
The Complete DSP Guide for Businesspeople and Nontechnical Professionals.
This site is full of well-written tutorials on wireless communications and DSP topics.
Instructor Rick Lyons' blog on DSP related topics makes for interesting reading on the subject.
