.SITE RENOVATION.

To all our members,

I (Kensei), have decided to renovate the site, which has remained dead since our head Administrator, Baraku, went absent. There will be a new set of rules, a new skin, new profile formats...

Basically, we're starting the site over.

But don't be alarmed. For those of you who choose to return, you will not have to rewrite your application, or change it to the present system. Your applications are still there, resting in the Filing Cabinet -- feel free and ask the Staff to repost it if it has already been approved, or ask them to read over the application and approve it, then move it to the Approved sub-boards.

If you do not wish to roleplay on the site any longer, or the renovation does not appeal to you, all you have to do is tell the Staff in a PM ; your account will be removed without any questions.

We apologize for any inconveniences, and thank you all for your patience and cooperation.


Your loving (new) head Admin,
Kensei

The theory of mechanical filters was first applied to improving the mechanical parts of phonographs in the 1920s. By the 1950s mechanical filters were being manufactured as self-contained components for applications in radio transmitters and high-end receivers. The high "quality factor", Q, that mechanical resonators can attain, far higher than that of an all-electrical LC circuit, made possible the construction of mechanical filters with excellent selectivity. Good selectivity, being important in radio receivers, made such filters highly attractive. Contemporary researchers are working on microelectromechanical filters, the mechanical devices corresponding to electronic integrated circuits.
