How many outputs are there in an octal-to-binary encoder?
the functons of encoder is reverse of the dec
What is a linear encoder used for?
A linear encoder is a instrument that uses precise measurements. A linear encoder is used on many different types of objects, but is used for the same purpose of measuring positions.
What are the applications of counters?
used in rotary shaft encoder
How do you use ic 7432 as an 8 to 3 bit encoder?
if you want to use 8*3 encoder than you must the design the circuit according to variable and with the help of k-map and you can not construct the circuit of 8*3 encoder using 7432 (which is or gate ic) only. you need AND gate 7408 and may be NOT 7404 gate according to design.
Vhdl code for 8 to 3 priority encoder?
karthika only know answer to this question
What kis difference between absolute and incremental encoders?
An absolute encoder can be used to find the absolute position whereas an incremental encoder is used to show how much you have moved.You can sometimes use an incremental encoder to get an absolute position provided that you always begin at a calibrated home point.Best regards,
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 an absolute encoder?
An absolute optical encoder is a type of rotary encoder. The optical disk is designed to produce a digital word which distinguishes N distinct positions of the shaft. Common types of numerical encoding used in the absolute encoder include gray and binary codes. http://www.motioncontrolguide.com/learn/guides/encoders-guide/
What is the difference between a microsyn and a selsyn?
a microsyn is an encoder while a selsyn is a synchro transmitter
How does a optical encoder work?
An incremental encoder is a pulse generator that provides square-wave signals and a zero index.The disc has 2 channels divided into "n" equal angular intervals; alternately opaque and clear. "n" is called resolution or number of counts.Pulses counted by the processing electronics give the angular position of the rotor. For this purpose 2 squarewaves A and B are used with a third channel, Z, synchronous with signals A and B giving only one signal per revolution. It allows the user to initialize or reset the count.Incremental encoder chartWhy another concept ?This concept has been developed to compensate for the performance limitations of incremental encoders :need for initializationmust be re-zeroed after a power interruption: zero reset to obtain the mechanism angular positionsensitivity to the interferenceThe absolute encoder supplies the shaft position as a binary code.The output code is unique for each position. The resolution is equal to 2n (n= number of bit).The shaft position information is given instantly when power is supplied.There are two different types of absolute optical encoders :Single turn absolute optical encoder -> gives the absolute angular position over 360° rotation.Multiturn absolute encoder -> a system of additional shafts and discs which allows the number of revolutions to be counted.The complete cycle is realized by « m » shaft rotations. The total resolution is equal to m x n (m=number of revolutions, n=number of counts per revolution).d
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 is a encoder motor?
An encoder motor is the part that engages the change between 4wd and 2wd.
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 are the characteristic of encoder?
It uses the previous few values of samples to predict the value of the next sample It encodes the difference between each actual signal and the predicted signal It reduces the number of bits to be sent
