Scalable latch requires no capacitors or clock - 19-Aug-04 Issue of EDN
Circuits that latch one-of-N switches usually use a digital approach. Such
circuits are often useful in human-interface situations, such as audio-mixing
consoles, video-feed selection, or current-loop-control redundancy systems. In
high-precision analog systems, such as high-fidelity audio or video, elimination
of clocking circuits, whenever possible, reduces the chances of coupling noise
back.... [Design Idea by Robert Most, Dow Corning S&T Electronics, Midland, MI] |

Scheme autodetects baud rate - 07/20/00 Issue of EDN The
popularity and easy access of RS-232 ports lend them to many communication
projects. You can use a port "as is" or as a tiny parallel port when the exchange
uses only control lines. Before the asynchronous serial-data transfer between two
devices can take place, you must ensure that both devices are configured to the
same data format and transmission rate. Usually, the OS utility or application
program on the host computer performs this task, which the OS or a combination of
switches selects in the peripheral. [Design Idea by Alexander Eisen, State
University of New York, Buffalo, New York] |

Scheme implements multiple output ports - 02/16/98 EDN-Design Ideas
In µP/µC systems, you sometimes need to use many output ports and update all the
ports simultaneously. For instance, in systems that use multiplexing techniques,
the output ports require refreshing for every scanning period. One example is a
system of multiple dot-matrix LEDs....File has many circuits, scroll to find this
one.... [Design Idea by W Kurdthongmee, Nakorn Si Thammarat, Thailand] |

Scheme improves on low-cost keyboard - 30-Oct-03 Issue of EDN You
can easily improve on a previous Design Idea to produce a slightly simpler
resistor arrangement with better timing balance between switches, using a single
resistor value (Reference 1, Figure 1]. The use of a single resistor value, RS, in
a series chain for the switch resistors gives the timing parameters a simpler
format and should reduce bill-of-materials cost.... [Design Idea by Martin O'Hara,
