left the market badly shaken. What happened? It appears that a single keystroke error was to blame. The letter “B” was inserted in a sell order instead of the letter “M”. Billion was input where Million should have been and it triggered a ripple effect through the automated financial markets. Costly errors in the events business might not have as many zeros as that epic fail, but when it’s your event or your exhibitor who has to deal with a problem caused by a keystroke mistake, it can seem just as bad. Today a surprising amount of venue managers and event organizers still work with separate CRM, operations, and financial systems that either require them to manually enter data multiple times, or have one-way information flow from system to system that can get out of sync. The result is costly – and often embarrassing – errors that stem from bad or out-of-step event detail data. But how acute is this problem? How exactly does it bleed energy and money from your organization? There are several ways in which poor or manual information flow can hinder your events business. The first issue is the cost of having a mistake creep into your information systems, customer orders, service or operation orders, or billing. You are particularly vulnerable if you have any manual “double-entry” of

(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 a data stream over a communication channel that https://en.wikipedia.org/wiki/Bit_error_rate have been altered due to 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 performance measure, often expressed as a percentage.[1] The bit error probability pe is the error rate 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 affecting the BER 4 Analysis of the BER 5 Mathematical draft 6 Bit error rate test 6.1 Common types of BERT stress acceptable error rate 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 independent of each other. For small bit error probabilities, this is approximately p p ≈ p e N . {\displaystyle p_{p}\approx p_{e}N.} Similar measurements can be carried out for the transmission of frames, blocks, or symbols.
