Orphan date February 2009 Notability Products date August 2011 A pseudorandom encoder is an electro mechanical device used for measuring distance and finding position. It is different from the conventional absolute and incremental encoder in its disk pattern, which gives it aspects of the other two designs. The disk of a pseudorandom encoder has an evenly spaced notch design just as an incremental encoder to measure distance. A second track of code is used to find the position just like an absolute encoder however, an absolute encoder tells position from reading from multiple parallel tracks while a pseudorandom encoder uses one single track. This aspect allows pseudorandom rotary encoders to have smaller diameters and larger through holes. To know its position, the encoder must first move a certain distance to read the code. This distance is generally small, about 1 2 degrees for rotary encoders and 1 mm for linear encoders, though this idiosyncrasy does hinder its usefulness in some applications such as trackball track balls since position is not immediately known when the system starts. ref cite web url http www.virtualabsolute.com VAoverview.htm title A New Kind of Encoder virtualabsolute.com ref See also Rotary encoder References reflist Category Dimensional instruments ... more details

A priority encoder is a Electronic circuit circuit or algorithm that compresses multiple Binary code binary inputs into a smaller number of outputs. The output of a priority encoder is the binary representation of the ordinal number starting from zero of the most significant input bit. They are often used to control interrupt request s by acting on the highest priority request. If two or more inputs are given at the same time, the input having the highest priority will take wikt precedence precedence ref M. Morris Mano, Michael D.

Harmonic and Individual Lines and Noise HILN is a parametric audio coding parametric codec for sound audio . The basic premise of the encoder is that most audio, and particularly speech, can be synthesized from only Sine wave sinusoids and noise. The encoder describes individual sinusoids with amplitude and frequency, harmonic tones by fundamental frequency, amplitude and the spectral envelope of the partials, and the noise by amplitude and spectral envelope. This type of encoder is capable of encoding audio to between 6 and 16 kilobits per second for a typical audio bandwidth of 8 kHz. The framelength of this encoder is 32 ms. A typical codec extracts sinusoid information from the samples by applying a short time Fourier transform to the samples and using that to find the important harmonic content of a single frame. By matching sinusoids across frames, the encoder is capable of grouping them into harmonic lines and individual sinusoids. The matching can take amplitude, frequency and phase into account when trying to match sinusoids across frames. Differences between amplitude and frequency within a track can be coded with fewer bits than each individual single sinusoid would require, thus the longer a track the encoder can find, the better it will be able to reduce the final bitrate . The decoder uses an add and overlap strategy each frame in the bitstream contains parameters for 32 ms, however, the next frame starts halfway through the current frame. By filtering the synthesized segments with a Hanning filter , adding two overlapping frames together will produce a smooth transition between the two. This also applies to the encoder because the short Fourier transform gives better results when the data is pre processed with a Hanning filter. Synthesizing only the sinusoids sounds artificial and metallic. To mask this, the encoder subtracts the synthesized sinusoids from the original audio signal. The residual is then matched to a linear audio filter filter that is ... more details

CCSDS 122.0 B 1 is a CCSDS Lossless to Lossy Image compression standard released on November 2005. This CCSDS standard is a discrete wavelet transform DWT transform coder followed by a Rice encoder & a Bitplane encoder on the similar lines as EZW Embedded Zerotree Wavelet by Shapiro. Encoder CCSDS 122.0 B 1 is a 3 Level 2D DWT using a biorthogonal 9 7 LPF HPF tap filters, followed by a bit plane encoder. It has some design commonalities with ICER and JPEG2000 that use similar wavelet coding schemes. The encoder can use either floating point or Integer DWT. Integer DWT is the lossless coding scheme, while the floating point DWT contributes to the lossy scheme. Lesser known features 9 7 INTEGER TRANSFORM An alternative transform in this Recommended Standard is a non linear approximation to a 9 7 DWT. This extra available non linear transform can be used to achieve lossless compression. Known flaws In the encoder s current form an image pixel dynamic range of up to 16 bits is supported, whereas ICER and JPEG2000 support 24 and 32 bitplanes. This compression format is sensitive to bit corruption in the deep space channel, but it is unclear if this sensitivity is greater than ICER or JPEG2000. The effects of a single bit error can propagate to corrupt reconstructed image data to the end of the affected segment. Measures must be taken to minimize the number of potential bit errors on the transmission link. There is a known partial fix, but it is not mandatory. The transport mechanism for the delivery of the encoded bitstream shall support, in the event of a bit error, the ability to relocate the header of the next segment. In case the encoded bitstream is to be transmitted over a CCSDS space link, several protocols that have built in error correction and detection can be used to transfer the sequence of segments the highest coding level in this image format . Lack of updates to the standard are also a problem, as the last revision to the encoder was in November 2005. Unli ... more details

Multiple issues expert subject September 2011 refimprove September 2011 context May 2009 An endec is a device which acts as both an encoding encoder and a encoding decoder on a Signal computing signal or data stream , either with the same or separate circuitry or algorithm. The combining of these names is a portmanteau . TOC Definition The general difference between an endec and a codec compressor decompressor is that hardware is usually considered to be an endec, while software is considered to be the codec. Dubious date May 2009 Similarly, the word encoding is usually used for hardware, while Code coding is usually used in regard to software. A device or program which uses a data compression compression algorithm to create MPEG sound audio and or video is often called an encoder, and one which plays back such files is a decoder. However, this is technically a codec, especially if performed in software . cn date September 2011 Examples Examples of encoders, decoders, and endecs include A modem is an endec, likewise a modulator is an encoder and a demodulator is a decoder An Emergency Alert System unit is usually an endec, but sometimes just a decoder A stereo generator used in broadcasting is an encoder A combination analog to digital converter ADC and digital to analog converter DAC would technically be an endec, though they are usually called CODECs Hardware that encodes data bits to a run length limited line code , and decodes the line code back to data bits, is an endec. ref United States Patent 5844507 ref When implementing the Infrared Data Association IrDA protocol, often an endec is used between the UART and the optoelectronics. ref http search.maxim ic.com search?q 22ENDEC 22&restrict english appnotes&site Maxim&output xml no dtd&client Maxim&num 20&proxystylesheet http 3A 2F 2Fwww.maxim ic.com 2Fsearch 2Fsearch3.xcgi&go Maxim IC search for endec app notes ref ref http infocenter.arm.com help index.jsp?topic com.arm.doc.ddi0183g I31065.html IrDA SIR ENDEC ... more details
