figure of merit

[′fig·yər əv ′mer·ət]
(analytical chemistry)
A performance characteristic of an analytical chemical method that influences its choice for a specific type of determination, such as selectivity, sensitivity, detection limit, precision, and bias.
(electronics)
A performance rating that governs the choice of a device for a particular application; for example, the figure of merit of a magnetic amplifier is the ratio of usable power gain to the control time constant.

figure of merit

The quantity used as the measurement of effectiveness of a system, typically electronic. The figure of merit (FOM) is determined by the primary characteristic that makes something fit for a specific purpose. For example, a digital camera's figure of merit is its sensor resolution, while a loudspeaker's is its frequency response. The figure of merit of an electronic circuit or system may be derived by an intricate algorithm.
