The power scaling of fiber lasers is limited by Raman scattering and Brillouin scattering, and by the fact that such lasers cannot be very long. The limited length of the double-clad fibers limits the usable power of the multi-mode pump, because the pump is not absorbed efficiently in the fiber's active core. Optimization of the shape of the ...
A variable L pad is a power divider circuit that provides an adjustable power level to a speaker while maintaining a constant load impedance on the amplifier. [ 1 ] Another approach uses a variac or power scaling circuit, which reduces the B+ supply voltage available to the power tubes thus producing power tube distortion at a reduced level ...
In computer architecture, dynamic voltage scaling is a power management technique in which the voltage used in a component is increased or decreased, depending upon circumstances. Dynamic voltage scaling to increase voltage is known as overvolting ; dynamic voltage scaling to decrease voltage is known as undervolting .
tech: approximate power of Galileo space probe's radio signal (when at Jupiter) as received on earth by a 70-meter DSN antenna. 10 −18: atto-(aW) 1 × 10 −18: −150 dBm phys: approximate power scale at which operation of nanoelectromechanical systems are overwhelmed by thermal fluctuations.

Automatic gain control of transmit power in radio frequency circuits; Scaling a large dynamic range sensor (e.g. from a photodiode [2]) into a linear voltage scale for an analog-to-digital converter with limited resolution [1] A log amplifier's elements can be rearranged to produce exponential output, the logarithm's inverse function.
According to some publications, at the power scaling of disk lasers, the round-trip gain should be reduced, [3] which means hardening [clarification needed] of requirement on the background loss. Other researchers believe the existing disk lasers work far from such a limit, and the power scaling can be achieved without modification of existing ...

It is an important scaling factor to maintain power efficiency. When referring to a junction field-effect transistor (JFET), the threshold voltage is often called pinch-off voltage instead.
