Disk Drives at 40: Lean Mean Storage Machines - 11/07/96 EDN-Design Feature
The disk drive may have turned 40 this year, but you won't find symptoms of middle age
creeping up on this all-star performer. New drives stretch to 9-Gbyte storage
capacities and achieve data transfer rates approaching 150 Mbps.... [Design Feature by

Dive Computer Interface - From the start, digital computers have required
some form of data storage as an adjunct to their relatively sparse mainstorage
facilities. Some of the early forms of storage were punched cards, paper tape and the
magnetic tape storage. This was the principal storage medium,....(National

Double DAC rate by using mixers as switches - 5-Feb-04 Issue of EDN
You can effectively double the sample rate of a DAC by interleaving two DACs into a
single unit. Updating each DAC on an alternating basis and switching to the
appropriate output double the effective throughput of the overall system. It is
essential to overall performance that you use a high-quality, high-speed switch in the
multiplexing of the DACs' outputs.... [Design Idea by Randall Carver, Analog Devices,
Greensboro, NC] |
