what is the working principle of encoder?

Encoder Working Principle. Encoders are used to translate rotary or linear motion into a digital signal. Usually this is for the purpose of monitoring or controlling motion parameters such as speed, rate, direction, distance or position.

Disadvantages: The biggest limitations of encoders are that they can be fairly complex and contain some delicate parts. This makes them less tolerant of mechanical abuse and restricts their allowable temperature. One would be hard pressed to find an optical encoder that will survive beyond 120ºC.

You must first convert the character to its ASCII value. In LiveCode, this is done with the charToNum function. Converting a number to the corresponding character is done with the numToChar function. The first of these statements converts a number to a character; the second converts a character to its ASCII value.

The FFT is lossless, so there's no compression as a result of using it. The compression is gained by perceptual modeling and dumping parts, and by powerful entropy modeling, like CABAC and such.

Data compression is the process of modifying, encoding or converting the bits structure of data in such a way that it consumes less space on disk. It enables reducing the storage size of one or more data instances or elements. Data compression is also known as source coding or bit-rate reduction.

In computers, encoding is the operation of placing a sequence of types (letters, numbers, punctuation, and certain symbols) into a specialized format for efficient transmission or computer memory. Decoding is the opposite process -- the conversion of an encoded format back into the original sequence of types.

Incremental rotary encoder outputs the pulse corresponding to the rotation angle only while rotating, and is the counting measurement method that adds up the pulse from the measurement beginning point. Absolute rotary encoder outputs the signal of position corresponding to the rotation angle by code.

['The additional bits are called parity bits. They allow detection or correction of the errors.', 'The data bits along with the parity bits form a code word.']

Lossy Data Compression: JPEG. Quantization is the process of reducing the number of bits needed to store an integer value by reducing the precision of the integer. Given a matrix of DCT coefficients, we can generally reduce the precision of the coefficients more and more as we move away from the DC coefficient.

2) When you create a multimedia file, you use a coder algorithms to encode the video and audio data, then you use a muxer to put the streams together into a file (container). To play the file, a demuxer takes apart the streams and feeds them into decoders to obtain the video and audio data.

Explanation: A bit-error rate tester (BERT) is used to test the functionality of a circuit; it does this by being able to generate testing patterns and measure the error rate of the pattern when it is received on the other side of the circuit.

Interpolation is the exact opposite of decimation. It is an information preserving operation, in that all samples of x[n] are present in the expanded signal y[n]. ... Interpolation works by inserting (L–1) zero-valued samples for each input sample. The sampling rate therefore increases from Fs to LFs.

A one hot encoding is a representation of categorical variables as binary vectors. This first requires that the categorical values be mapped to integer values. Then, each integer value is represented as a binary vector that is all zero values except the index of the integer, which is marked with a 1.

Run-length encoding (RLE) is a form of lossless data compression in which runs of data (sequences in which the same data value occurs in many consecutive data elements) are stored as a single data value and count, rather than as the original run.

Data encoders do much more than type on a keyboard all day. A data encoder job description typically includes duties such as entering data, maintaining databases and client files, managing hard copies, scanning documents and handling other data-related tasks.

There are video Encoders and decoders. The encoders convert analog video to a digital signal that connects to the network. It allows you to use an older analog camera with the latest IP camera system. The decoder converts digital video signals to an analog video signal.
