Encoder is usually used to measure the speed of a motor or a conveyor and provide feedback to the control system. In this case, the encoder reads the speed of the elevator and gives feedback to its control system
What is rf transmitter
An encoder is a digital circuit which accepts one of the inputs and converts it into BCD or Binary Coded Output. It performs the reverse function of that of a decoder.
A binary encoder is a person who creates a code used to program computers at the most basic level. Claude Shanna developed binary encoding in the 1930s.
To select particular data at particular situation.
source decoder is an automated source code analyzer. It is a complememt to source encoder. It retrieves the information from the encoded signal. We can say that source decoder decodes the coming signal to extract the information oit of it.
A rotary encoder consists of three main parts: light source, optical encoder disc and light sensors. The light source provides the light source to several light sensors. There is an optical encoder disc that selectively blocks light from light source to light sensor. If the light sensor is receiving light, it is first state of electronic circuit. If the light from light source to the sensor is blocked by optical encoder, then sensor is not receiving light and this is second state of sensor output. Therefore, each sensor has two ouputs possible, high or low. Output from one sensor is called a "bit" so for 4 sensors, it is 4 bit output. The light encoder disc is a plastic disc with some area opaque and other areas transparent. Depending upon its rotating position, it passes light to some sensors and blocks light to other remaining sensors. The combination of states of multiple light sensors at a given time due to a certain rotary position of rotary encoder disc is the multi-bit output of that rotary encoder. This multi-bit logic output is used to sense the position, direction of rotation and rotating speed of the rotary encoder. You can read more about rotary encoders at the links given.
A shaft encoder is also known as a rotary encoder. The shaft encoder converts an angular position of a shaft to a digital code.

Yes.

A normal encoder get proper output when input is asserted atmost one at a time. i.e if I0 I1 I2 I4 are inputs of 2to4 decoder then if the both inputs I1 and I2 are given then the output maybe 11 or 00 but not 01 or 10. In pripority encoder assigns priority to inputs, If encoder have I2 high priority than I1 and both I1 and I2 are applied '10' will be output.
You can get an encoder online at Microsoft's website. There is a free version you can get and also a version of Microsoft Expression Encoder that you may buy.
A source encoder converts client input to a binary stream. This is typically done by sampling an analog input, digitizing the samples and coding them into a binary stream. A common component that does all this is called a Codec. A channel encoder converts a binary stream to an analog signal that can be transmitted over distances as tones, radio waves and/or light. The channel encoder can take a number of bits from the bitstream at a time to create a multibit symbol. The symbols can then be converted to an analog signal for transmission. By transmitting symbols that represent multiple bits, more data can be sent without violating the Nyquist criteria. However, the number of bits that can be coded into a symbol is limited by the SNR as in Shannon's law. A common component that does all this is called a Modem.
