Dimmer - Dimmers are devices used to vary the voltage running to a light. By decreasing or increasing the voltage to the lamp it is possible to vary the intensity of the lamp. Changes in intensity are called “. Used . fades” and can be “fade ups” or “fade downs.” Although variable-voltage devices are used for various purposes, the term dimmer is generally associated with lighting control. Small dimmers are. Used . seen more and more in the home. These have traditionally been actuated by direct control. The advent of X-10 technology is making remote control of home dimmers possible. A digital signal is imposed on the ho...

Amplitude - Amplitude is a nonnegative scalar measure of a wave's magnitude of oscillation, that is, magnitude of the maximum disturbance in the medium during one wave cycle.

Sometimes this distance . Used . is called the "peak amplitude", distinguishing it from another concept of amplitude, used especially in electrical engineering: the root mean square (RMS) amplitude, defined as the square roo. Used . t of the temporal mean of the square of the vertical distance of this graph from the horizontal axis. The use of peak amplitude is unambiguous for symmetric, periodic waves, like a sine wave, a square wave, or...
