[2] In his subsequent career at the University of Edinburgh he initiated the Department of Electrical Engineering, establishing its capabilities in silicon device processing and enhancing industrial interactions through Wolfson Microelectronics.
He subsequently met with Churchill's scientific adviser, R V Jones, and assisted in detecting the signals from the enemy navigator aids used to direct bombers on to target.
One of Farvis’ major wartime achievements was to counteract a sophisticated new German navigation aid, "Benito", with Alex Harley Reeves, the later inventor of pulse code modulation telephony.
In 1969, Farvis set up of the Wolfson Microelectronics Liaison Unit (WMLU), coinciding with the first appointment of part-time paid visiting Professors in a UK university.
Many of his post-war innovations in the undergraduate curriculum were tried out at Edinburgh before catching on elsewhere, including: open book examinations, individual experimental project work, and in-depth dissertation writing.
