Instruments Many modern laboratory instruments digital error correction use digital displays. For example, you can measure weights using

the central value of your measurement. It will give you the central value. All you have to do is write it down. Now,

what is the error of this seemingly "precise" measurement? All instruments, no matter how sophisticated, have a limit to their precision. Usually, the manufacturer of the instrument will specify the error. (Most of the time it is written on the back of the instrument.) However, if neither you error on digital pregnancy test nor your laboratory instructor can find this information, use the following rule of thumb: The error of an electronic device is usually half of the last precision digit. The following example should make it clear. Suppose you measured your weight with the electronic device pictured above. The result is 138.2 lbs. What is the error? If you can't find the manufacturer information about the error, you notice that the resolution of your measurement is 0.1 lb. In other words, the device claims that it can give you a more precise value than 138 lbs, but it doesn't tell you whether your weight is 138.15 lbs or 138.25 lbs. Thus we can assume that the error of our measurement is 0.05 lb. And our answer is 138.2 lbs ± 0.05 lb. << Previous Page Next Page >> Home - Credits - Feedback © Columbia University

be challenged and removed. (March 2013) (Learn how and when to remove this template message) In digital transmission, the number of bit errors is the number of received bits of https://en.wikipedia.org/wiki/Bit_error_rate a data stream over a communication channel that have been altered due to http://support.kaspersky.com/us/8894 noise, interference, distortion or bit synchronization errors. The bit error rate (BER) is the number of bit errors per unit time. The bit error ratio (also BER) is the number of bit errors divided by the total number of transferred bits during a studied time interval. BER is a unitless error in performance measure, often expressed as a percentage.[1] The bit error probability pe is the expectation value of the bit error ratio. The bit error ratio can be considered as an approximate estimate of the bit error probability. This estimate is accurate for a long time interval and a high number of bit errors. Contents 1 Example 2 Packet error ratio 3 Factors error in digital affecting the BER 4 Analysis of the BER 5 Mathematical draft 6 Bit error rate test 6.1 Common types of BERT stress patterns 7 Bit error rate tester 8 See also 9 References 10 External links Example[edit] As an example, assume this transmitted bit sequence: 0 1 1 0 0 0 1 0 1 1 and the following received bit sequence: 0 0 1 0 1 0 1 0 0 1, The number of bit errors (the underlined bits) is, in this case, 3. The BER is 3 incorrect bits divided by 10 transferred bits, resulting in a BER of 0.3 or 30%. Packet error ratio[edit] The packet error ratio (PER) is the number of incorrectly received data packets divided by the total number of received packets. A packet is declared incorrect if at least one bit is erroneous. The expectation value of the PER is denoted packet error probability pp, which for a data packet length of N bits can be expressed as p p = 1 − ( 1 − p e ) N {\displaystyle p_{p}=1-(1-p_{e})^{N}} , assuming that the bit errors are ind
