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 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.

Operating Modes of Dynamic Power Supply Transmitter Amplifiers
Any amplifier operated with a varying supply voltage is actually a three-port circuit, having two inputs and one output. When an amplifier is characterized as a three-port for dynamic supply voltage operation, three separate operating modes...
