A figure of merit for digital filters
ICASSP '78. IEEE International Conference on Acoustics, Speech, and Signal Processing, 2005The combined effects of amplitude quantization are brought together in such a way that the designer can readily choose cost effective word lengths for his A-D converter and digital filter. A degradation factor is suggested which relates the performance of the digital circuit to its analog counterpart in terms of the filter's frequency transfer ...

International Astronomical Union Colloquium, 1997
AbstractWe develop a figure of merit for SETI observations which is anexplicitfunction of the EIRP of the transmitters, which allows us to treat sky surveys and targeted searches on the same footing. For each EIRP, we calculate the product of terms measuring the number of stars within detection range, the range of frequencies searched, and the number ...

Transducer figure of merit (L)
The Journal of the Acoustical Society of America, 2012An alternative formula for determining the volume-referenced, projector-transducer figure of merit, FOMv, is developed allowing an evaluation based on well known parameters that may be readily calculated or measured. This formula is also reduced to the special case of piezoelectric or magnetostrictive materials, allowing a FOMv comparison of transducer

An improved figure of merit for symbol synchronisers
ICC 2001. IEEE International Conference on Communications. Conference Record (Cat. No.01CH37240), 2002The contribution of this paper is to derive a novel figure of merit that can be measured in practice for symbol synchronisers. It is used to estimate the probability of symbol error, including the effect of symbol slip, for different frame and signaling alphabet sizes.

Figures of merit are values that denote the benefit of key material properties in terms of mechanical and thermal performance. Mechanical figures of merit relate to stiffness, strength, and mass. The stiffness of a material is proportional to its elastic modulus E, while the mass of a material is proportional to its density ρ.

Figure of merit for thermoelectrics
Journal of Applied Physics, 1989Theoretical calculations are presented for the figure of merit Z in thermoelectrics. The maximum values of Z are obtained in semiconductors which are doped so that the chemical potential is near the band edge. The highest Z is related to the B parameter of Chasmar and Stratton [J. Electron. Control 7, 52 (1959)].

Improved figures of merit for direct methods
Acta Crystallographica Section A Foundations of Crystallography, 1992The figures of merit (FOMs) proposed in a recent paper [Cascarano, Giacovazzo & Viterbo (1987). Acta Cryst. A43, 22–29] are modified to improve their efficiency. It is shown that FOMs based on psi-zero triplets and FOMs based on the distribution of the concentration parameter α can be treated by the same mathematical formalism.

To analyze, quantify, and compare the performance of infrared (IR) imaging devices, such as various types of focal plane arrays (FPAs), it is essential to have an in-depth understanding of their figures of merit. In this entry, we discuss a series of figures of merit that are applicable to both cooled and uncooled IR detectors and systems. We provide a

Reliability as a Figure of Merit
2016An electric power converter is specified by its system performance indices. Many system performance indices like efficiency are important in design process of system. However, that doesn't mean the converter performance is necessarily adequate for a practical application.
