Hi All !

Telefunken was the company alright, but if memory serves the 
multiband system was called Telcom, and used extensively in the 
broadcast sector .  The Highcom system was a single band noise 
reduction system, designed for consumer applications .  Elector 
published a project using the modules .

Dolby a-b-c used tunable filters as active elements .  SR/S use a 
similar ploy as the Telefunken system .

Cheers .


Keep 'em oscillating :)
