History, applications, and subsequent development of the FXLMS Algorithm [DSP History]

The guest in this column is Dr. Dennis R. Morgan. Destined to have a stellar engineering career, Dr. Morgan started experimenting in the family basement workshop with all sorts of electrical experiments only a few years after he had learned to read. In sixth grade, he read books about radio and electronics and used that knowledge to repair a radio, the first of many. He pursued his electronic calling, converting the family workshop into an electronics laboratory, where he continued all sorts of investigations, repairs, and built many kits, which included a 5-in oscilloscope (which he built while he was a high school sophomore). Later that year, he obtained his first part-time job in a radio repair shop, where he continued to work part time throughout high school and college, learning many practical tricks of diagnosis and troubleshooting involving measurements, logic, and often 'tapping' around for intermittent problems.
