ITU-R V.574 - Use of the decibel and the neper in telecommunications
August 1, 2015 - ITU-R

This text recommends the symbols to be used for the logarithmic expression of quantities referring to power, and provides examples of the use as well as the relationship between the decibel and the neper.

ITU-T G.100.1 - The use of the decibel and of relative levels in speechband telecommunications
June 1, 2015 - ITU-T

In transmission engineering, most often it would be rather impractical to characterize the magnitude of signals directly by a numerical value in volts or watts. Instead, a logarithmic measure is used, expressed in "dB", to characterize the signal magnitude in relation to some chosen reference value...

Combination of Levels in dB
December 1, 2017 - ESDU

Methods are provided to deal with the combination of sound pressure levels in decibels. Firstly, for the case when several sources are acting together a method of addition is given to estimate the combined sound pressure level in dB from all the sources. Secondly, for the measurement of...

Pocket Radar Guide: Key facts, equations, and data
January 1, 2010 - IET

The book covers the following topics about radar concept; frequency; antennas; transmitters; receivers and signal processor; waveforms; radar cross-section; radar equation; detection and search; measurement and tracking; clutter; atmosphere, rain and ionosphere; decibels (dB), and list of...

The relation between sound pressure level and r.m.s. fluctuating pressure.
September 1, 1978 - ESDU

ESDU 66018 provides a means of converting a sound pressure level in decibels to a root mean square value of fluctuating pressure. These data are often required when estimating structural loadings from noise data. Data are provided as equations for r.m.s. fluctuating pressures in both British...

Principles of Modern Radar: Basic principles
January 1, 2010 - IET

This book is divided into 4 major parts: the first part deals with radar overview, radar range equation and radar detection in interference; the second part covers the different radar environment, such as clutter, target reflectivity, etc.; the third part focuses on radar subsystems, such as...

ASTM F2504 - Standard Practice for Describing System Output of Implantable Middle Ear Hearing Devices
November 1, 2005 - ASTM

This practice defines means for describing system performance (ex vivo) and, in particular, system output of an implantable middle ear hearing device (IMEHD) by measuring a physical quantity that is relevant to the insertion gain and output level of the IMEHD when implanted in the patient. This...

ANSI/ASA S3.4 - AMERICAN NATIONAL STANDARD Procedure for the Computation of Loudness of Steady Sounds
May 24, 2007 - ASA

This standard specifies a procedure for calculating the monaural and binaural loudness experienced by listeners with normal hearing under the following conditions: Listening conditions. The standard applies to three listening conditions: free field with a frontal incidence, diffuse field, or...

TIA-455-201 - FOTP-201 Return Loss of Connectorized Polarization-Maintaining Fiber or Polarizing Fiber Pigtailed Devices and Cable Assemblies
August 8, 2001 - TIA

Intent This Standard specifies a procedure for the measurement of the return loss of a fiber optic interconnection on single mode, highly linearly birefringent optical fiber, i.e. either polarization-maintaining (PM) fiber or polarizing (PZ) fiber. The connector can be mounted on the PMF/PZF...
