Orphan date February 2009 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 circuit or algorithm that compresses multiple 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 precedence . An example of a single bit 4 to 2 encoder is shown, where highest priority inputs are to the left and x indicates an irrelevant value i.e. any input value there yields the same output since it is superseded by higher priority input. class wikitable style margin 0 style border bottom 2px solid 000 I sub 3 sub style border bottom 2px solid 000 I sub 2 sub style border bottom 2px solid 000 I sub 1 sub style border bottom 2px solid 000 I sub ... 1 caption 4 to 2 priority encoder Priority encoders can be easily connected in arrays to make larger encoders, such as one 16 to 4 encoder made from six 4 to 2 priority encoders four 4 to 2 encoders having ... four as input.

An auto encoder is an artificial neural network used for learning efficient codings. The aim of an auto encoder is to learn a compressed representation encoding for a set of data. This means it is being used for dimensionality reduction . More specifically, it is a feature extraction method. Auto encoders use three or more layers An input layer. For example, in a face recognition task, the neurons in the input layer could map to pixels in the photograph. A number of considerably smaller hidden layers, which will form the encoding. An output layer, where each neuron has the same meaning as in the input layer. If linear neurons are used, then an auto encoder is very similar to principal components analysis PCA . Training An auto encoder is often trained using one of the many backpropagation variants conjugate gradient method , steepest descent , etc. Though often reasonably effective, there are fundamental problems with using backpropagation to train networks with many hidden layers. Once the errors get backpropagated to the first few layers, they are minuscule, and quite ineffectual. This causes the network to almost always learn to reconstruct the average of all the training data. Though more advanced backpropagation methods such as the conjugate gradient method help with this to some degree, it still results in very slow learning and poor solutions. This problem is remedied by using initial weights that approximate the final solution. The process to find these initial weights is often called pretraining. A pretraining technique developed by Geoffrey Hinton for training many layered deep auto encoders involves treating each neighboring set of two layers like a Boltzmann machine Restricted Boltzmann Machine Restricted Boltzmann Machine for pre training to approximate a good solution and then using a backpropagation technique to fine tune.

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 fequency, 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 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 preprocessed 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 excited with ... more details
