  1. Insertion loss

    In telecommunications , insertion loss is the loss of Signalling telecommunication signal power physics power resulting from the insertion of a device in a transmission line or optical fiber and is usually expressed in decibel s dB . If the power transmitted to the load before insertion is P sub T sub and the power received by the load after insertion is P sub R sub , then the insertion loss in dB is given by, math 10 log 10 P mathrm T over P mathrm R math Electronic filters Insertion loss is a figure of merit for an electronic filter and this data is generally specified with a filter. Insertion loss is defined as a ratio of the signal level in a test configuration without the filter installed V sub 1 sub to the signal level with the filter installed V sub 2 sub . This ratio is described in decibel dB by the following equation math mbox Insertion loss dB 10 log 10 left V 1 right 2 over left V 2 right 2 20 log 10 left V 1 right over left V 2 right math Note that, for most filters, V sub 2 sub will be smaller than V sub 1 sub . In this case, the insertion loss is positive and measures how much smaller the signal is after adding the filter. Link with Scattering parameters In case the two measurement ports use the same reference impedance, the insertion loss math IL math is defined as ref Pozar, David M. Microwave Engineering, Third Edition ref ref Collin, Robert E. Foundations For Microwave Engineering, Second Edition ref math IL 20 log 10 left S 21 right , text dB math and not, as often ... dB. It is the extra loss produced by the introduction of the DUT between the 2 reference planes of the measurement.

  1. Gap loss

    Image Gap loss en .svg right thumb 350px Gap loss in action Gap loss is a type of signal strength loss that occurs in Optical fiber fiber optic transmission when the signal is transferred from one section of Optical fiber fiber or cable to another. ref name dicdef cite book title Communications Standard Dictionary author Martin H. Weik year 1996 publisher Springer isbn 0412083914 ref The three basic types of gap loss are angular misalignment loss, lateral offset loss, and longitudinal displacement loss. The losses tend to be proportional to the ratio of the core radius to the size of the gap or displacement. Formulas, examples and graphs can be found at http www.engr.sjsu.edu kghadiri EE164 Lecture Notes Lecture 2017 20 20Fiber 20Optic 20Communication 20 20Coupler 20and 20Connector.pdf Fiber Optic Communication Couplers and Connectors Gap loss can be reduced by filling the gap with a gel that matches the index of refraction of the fiber as closely as possible. Definition Specifically, gap loss happens when the signal from one end of a piece of cable is transferred to another, but there is a space, breakage, or gap between them. Since fiber optics transmit data via light the light can cross this gap, but spreads out and is weakened and diffused when it does so. The light that crosses the gap and enters the next section of cable is broken up. Some of it reflects off, and some will hit the covering of the cable and not enter into the cable. If the gap is small, the gap loss will be small, but if the gap is very large, it may totally corrupt the signal. ref name interest cite book ... coauthors Baksheesh Ghuman year 2001 publisher Sams Publishing isbn 067232248X ref Gap loss can be caused ... be a loss of signal. ref name mneh cite book title Technician s Guide to Fiber Optics author Donald ... of gap loss As a result of signal strength and cohesion being lost due to the scattering of the light , a fiber optic signal suffering from gap loss is degraded in both quality and throughput.

  1. Loss of significance

    Unreferenced date September 2009 Loss of significance is an undesirable effect in calculations using floating point floating point arithmetic. It occurs when an operation on two numbers increases relative error substantially more than it increases absolute error , for example in subtracting two large and nearly equal numbers known as catastrophic cancellation . The effect is that the number of significant digit accurate significant digits in the result is reduced unacceptably. Ways to avoid this effect are studied in numerical analysis . The phenomenon can be demonstrated with decimal numbers. The following example demonstrates loss of significance for a decimal floating point data type with 10 significant digits Consider the decimal number 0.1234567891234567890 A floating point representation of this number on a machine that keeps 10 floating point digits would be 0.1234567891 which is fairly close the difference is very small in comparison with either of the two numbers. Now perform the calculation 0.1234567891234567890 0.1234567890 The answer, accurate to 10 digits, is 0.0000000001234567890 However, on the 10 digit floating point machine, the calculation yields 0.1234567891 0.1234567890 0.0000000001 Whereas the original numbers are accurate in all of the first most significant ... to loss of significance.

  1. Loss reserving

    Citation needed date August 2011 Loss reserving or Outstanding claims reserves refers to the calculation of the required reserves for a tranche of general insurance business. ref name BornFerg http www.variancejournal.org issues 02 01 85.pdf The Bornhuetter Ferguson Principle ref Typically, the claims reserves represent the money which should be held by the insurer so as to be able to meet all future Claim legal claims arising from policies currently in force and policies written in the past. Methods of calculating reserves in general insurance are different from those used in life insurance , pension s and health insurance since general insurance contracts are typically of a much shorter duration. Most general insurance contracts are written for a period of one year. Typically there is only one payment of Insurance premium premium at the start of the contract in exchange for coverage over the year. Reserves are calculated differently to contracts of a longer duration with multiple premium payments since there are no future premiums to consider in this case. The reserves are calculated by forecasting future losses from past losses. The more popular statistical methods in claims reserving are the Chain Ladder Method and the Bornhuetter Ferguson Method. The Chain Ladder Method uses data in a two dimensional array representing occurrence and development of claims. The upper left of this matrix contains known values in the past which are used to estimate the remaining figures i.e. arising in the future . The Bornhuetter Ferguson Method is a Bayesian technique. This means that it incorporates both an independently derived prior estimate of ultimate expected losses as well as estimates generated by the same kind of matrix described above. These are weighted by what is called a credibility factor, ideally giving preference to the more reliable projection, but taking both into consideration. ref name BornFerg references Category Insurance terms ...   more details

P mathrm r math where RL dB is the return loss in dB, P sub i sub is the incident power and P sub r sub is the reflected power. Return loss is related to both standing wave ratio SWR and reflection coefficient . Increasing return loss corresponds to lower SWR. Return loss is a measure of how well devices or lines are matched.
