In telecommunication and information theory , the code rate or information rate ref Huffman, W. Cary, and Pless, Vera, Fundamentals of Error Correcting Codes , Cambridge, 2003. ref of a forward error correction code is the proportion of the data stream that is useful non redundant . That is, if the code rate is k n , for every k bits of useful information, the coder generates totally n bits of data, of which n k are redundant. If R is the gross bitrate or data signalling rate inclusive of redundant error coding , the net bitrate the useful bit rate exclusive of error correction codes is R k n . For example The code rate of a convolutional code may typically be 1 2, 2 3, 3 4, 5 6, 7 8, etc, corresponding to that one redundant bit is inserted after every single, second, third, etc, bit. The code rate of the Reed Solomon block code denoted RS 204,188 is 188 204, corresponding to that 204 188 16 redundant bytes are added to each block of 188 byte of useful information. A few error correction codes do not have a fixed code rate rateless erasure code s.

cleanup date March 2012 A rate gyro is a type of gyroscope , which rather than indicating direction, indicates the rate of change of angle with time. If a gyro has only one gimbal ring, with consequently only two planes of freedom, it can be adapted for use as a rate gyro to measure a rate of angular movement. Rate gyros are used in rate integrating gyroscope s, and in attitude control system s for vehicles, and in combination with other sensors to make inertial navigation system s. The advantage of rate gyros over other types of gyros is the fast response rate and their relatively low cost. Principles Spinning The traditional type of rate gyro employs relatively convention gyroscopes with viscous couplings to transfer the spin rate to allow it to be read. Vibrating structure gyroscope main Vibrating structure gyroscope MEMS gyros are cheap and have no moving parts. They often work by sonic resonance effects driven by piezoelectric transducers, that provide a signal when a rotation occurs.

A reference rate is a rate that determines pay offs in a financial contract and that is outside the control of the parties to the contract. It is often some form of LIBOR rate, but it can take many forms, such as a consumer price index , a house price index or an unemployment rate . Parties to the contract choose a reference rate that neither party has power to manipulate. Examples of use The most common use of reference rates is that of short term interest rates such as LIBOR in floating rate note s, loan s, swap finance swaps , short term interest rate futures contract s, etc. The rates are calculated by an independent organisation, such as the British Bankers Association BBA as the average of the rates quoted by a large panel of banks, to ensure independence. Another example is that of swap reference rates for constant maturity swap s. The rate that is used is calculated daily by an independent organisation, the International Swaps and Derivatives Association , from quotes from a large panel of banks. In the credit derivative market a similar concept to reference rates is used. Pay offs are not determined by a rate , but by possible events . In this case, the reference event has to be a very precisely defined credit event , to make sure there can be no disagreement on whether the event has occurred or not. Typically the benchmark LIBOR is the three month rate. Reference rates for short term interest rates Examples of reference rates for short term interest rates are Euribor Euro Interbank Offered Rate LIBOR London Interbank Offered Rate SIBOR Singapore Interbank Offered Rate TIBOR Tokyo Interbank Offered Rate WIBOR Warsaw Interbank Offered Rate MIBOR Mumbai Inter Bank Offer Rate MIBOR Mumbai Interbank Offered Rate KIBOR Karachi Interbank Offered Rate Category Interest rates ca Tipus d inter s de refer ncia de Referenzzinssatz fr Taux de r f rence id Kurs referensi pl Stawka referencyjna fi Viitekorko ... more details

unreferenced date June 2009 The field rate of an interlaced video image is twice the effective frame rate , since interlacing draws only half of the image the odd or even numbered lines at a time. For example, a field rate of 60 Hertz will correspond to a 30 frames per second moving picture. A field rate can apply to either a video signal, or to a monitor designed to display that signal without conversion. Theoretically, an interlaced signal could have three or more fields per frame, resulting in a field rate that is a 3x or higher multiple of the frame rate. However no such signal is in common use today. Progressive scan monitors do not have a field rate, however they may still display interlaced video by converting each field into a full frame, a process called deinterlacing . In this case, the monitor s frame rate would then likely match the video signal s field rate. physics stub Category Film and video technology ... more details
