|John Edwards is keenly interested in
applying DSP to solve real-world problems. This interest
started while he was studying at The University of
Bradford and was sponsored by Lion Systems Developments
Ltd., a supplier of voice-band modems. After graduating,
John joined the development team at Lion that was tasked
with developing one of the first V.32 modems based on a
general purpose DSP. John's personal responsibilities
included developing the trellis coded modulator (TCM) and
associated Viterbi decoder, the call progress monitoring
filters, telephone line quality analyser and a simulator
for phase-roll (a modulation side-effect often
experienced over satellite links).
1987 John moved to Brush Electrical Machines Ltd. working on the power
generation management systems and also in the Automotive Test Systems
Group where he was part of a team developing rolling roads for testing
vehicle performance - a really cool and job with a fantastic team of
peopel, but not quite DSP. In 1990 John moved to
Loughborough Sound Images, to help form the Applications Group, of
which he went on to become the Group Manager. In 1998 LSI merged with
Mizar Inc. to form Blue Wave Systems, which was purchased by Motorola
Computer Group in 2001, where he was DSP Technical Marketing Manager.
John finished at Mototola in 2006, when they closed the office.
Following Motorola he then worked full time at Numerix on some very
contracts in the Industrial, Automotive and Aerospace industries. In
January 2007 John was offered and took the job of Senior FAE at
picoChip Designs Ltd, where he supported their customers in WiMAX, WCDMA and LTE markets. In February 2013 John was offered a job that he just couldn't
refuse, as European FAE for XMOS Semiconductors Ltd, supporting customers in USB Audio, AVB, Industrial Comms and Motion/Motor Control applications.
John is a visiting lecturer at The University of Oxford where he teaches DSP as part of the Summer Engineering Program For Industry. John was also a visiting lecturer at Loughborough University, where he taught DSP, for 15 years, as part of the MSc course in Digital Communication Systems. John also taught DSP classes at the Embedded Systems Conferences, in the USA and Europe for around 15 years. Prior to that, John was a long standing member of the Technical Review Committee and the Industrial Advisory Board for DSP World / ICSPAT and laterly GSPx.
For 4 years John was a member of the England Canoe Slalom Team and regularly competed at international level on white-water in the UK and Europe. After standing down from the daily grind of training, training and more training, to concentrate on his career, John built a rally car with his brother and spent a couple of years entering local car rallies. John's hobbies now include snowboarding and playing guitar.
In 2013 John started the Real Gone Geek Blog to try to document some of the DSP related knowledge that has accumulated in his head.
