DSP Digital Signal Processing

Digital signal processing plays an important role in implementing transceiver functions after a signal has been digitized.

Rick Lyons on Using the Forward FFT Algorithm to Compute the IFFT

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.

New Post Regarding Goertzel Filters from Rick Lyons on DSPRelated

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."

Complex to Real Website


Charan Langton

This site is full of well-written tutorials on wireless communications and DSP topics.

Communications is not an easy science. The math is heavy, and intuition is slow to develop. To complicate things further, the field does not stay put. New concepts are always coming to the fore.

This website offers tutorials I have written on various topics in analog and digital communications that will help you cut through this complexity. I keep adding to this collection, albeit very slowly.
