Instructor Ali Darwish has co-authored a couple of new papers recently. The most recent one, A Broadband 1-to- N Power Divider/Combiner With Isolation and Reflection Cancellation appears in the IEEE MTT Transactions. You must be a member of the IEEE Microwave Theory and Techniques society to get free access.
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.

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 Earl McCune has written a new book on envelope tracking for power amplifiers. Look for him to teach a course on the topic with Besser Associates as well.
Wireless voice and data communications have made great improvements, with connectivity now virtually ubiquitous. Users are demanding essentially perfect transmission and reception of voice and data. The infrastructure that supports this wide connectivity and nearly error-free delivery of information is complex, costly, and continually being improved.
Tim Wescott has joined Besser Associates with a new course on Applied Embedded Control Systems.
Christopher Baker has joined Besser Associates with his new course on Modern Radar Systems.
Use this handy Smith Chart web app to create matching networks. Easiest tool to use: drag elements right on the chart! Supports multiple frequencies, transmission line elements, etc.
