List the difference between encoder and priority encoder?
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.
What are the disadvantages of priority encoder?
For a priority encoder, priority is given to that input that has a larger value compared to the others. i.e., if for a 3 bit output, we have both 6 and 3 as active, then 6 is given priority over 3 and the output will be 110
What is encoder explain in brief?
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.
How does light behave to make rotary encoder work?
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.
How does the rotary encoder work?
A rotary encoder is a type of position sensor which is used for defining the angular position of a rotating shaft. It generates an electrical signal, either equivalent or digital, according to the rotational movement. There are numerous types of rotary encoders like: absolute rotary encoder, incremental rotary encoder Light Duty Incremental Encoders and many other. These encoders are categorized by either Output Signal or Sensing Technology.
What is difference between encoder and multiplexer in digital electronics?
An encoder refers to a device that is used to change a signal or data into a code. Whereas a Multiplexer or mux is a device which performs multiplexing or it takes information from more than one channels and outputs into a single channel. Thus a multiplexer is basically a kind of encoder where its function is to combine multiple inputs into one output.
How does shaft encoder work?
A shaft encoder is also known as a rotary encoder. The shaft encoder converts an angular position of a shaft to a digital code.

What decoder chip converts 7 lines to 3 lines?
Decoder is a circuit which have n inputs and 2^n outputs.I think you want to say encoder which have 2^n input and n output lines. So your required chip is 8(2^3)X3 encoder which does not exist.
