- Abstract
- Digital systems are technically attractive for the delivery of high quality audio to the home because they can be substantially transparent even under conditions of impaired reception, and permit scrambling without degradation in quality. Conventional multilevel pulse code modulation (pcm), with its precise D-A converters (at least 13-bit), elaborate output filters and complex error correction, can perform very well, but its cost is much higher than that normally associated with consumer audio circuitry. This paper describes a digital transmission technique based on delta modulation, whose decoder cost is a small fraction of that of a pcm system.

bio
Kenneth Gundry was born in 1943 in Bedford, England. In 1965 he received an M.A. in electrical engineering from Cambridge University. He joined the British Broadcasting Corp., first as a television engineer and later as a designer of audio control equipment for studios. In 1971 he moved to the research and development department of Dolby Laboratories, where his activities have included the design of integrated circuits for Dolby B- and C-type noise reduction and of numerous professional products, the development of methods to improve low-speed analog magnetic recording and research into more economical digital audio techniques. He holds several patents in these fields. - Copyright
