Method of eliminating absolute encoder voltage variations in circuits

eliminatingAbsolute encoder voltageThe problem expected with this design will be the generation of deviations: the error of the 3% may cause the voltage to vary between 3V and 4.5V. The incremental encoder corresponds to a defined digital code for each position, so that its indicated value is only related to the start and end positions of the measurement and not to the intermediate processes of the measurement. Basic calculations can be performed. The digital absolute encoder is 50kΩ (25% tolerance), R1 is 16.5K , R2 is 100K . The absolute encoder end-to-end resistance 25% tolerance is the largest source of error in the design.

　　Now consider the same calculation with different tap resistors, if the absolute value encoder is 37.5kΩ the top voltage will be 4.46V and the low side will be 3.25V; if the absolute value encoder is 62.5kΩ the top voltage will be 4.54V and the low side voltage will be 2.79V.This circuit, due to the large deviation of the absolute value encoder's end-to-end resistance, cannot be solve the voltage variation problem using this basic architecture. Tie-bit encoders are devices that convert signals or data compilations into a form usable for communication, transmission and storage, converting angular or linear displacements into electrical signals, the former known as a code disk and the latter known as a code scale. Encoder signal outputs include sine wave, square wave, open collector, push-pull, and many other forms.

　　The introduction of two voltage references in the circuit keeps deviations and temperature coefficients under control. The end-to-end absolute deviation of the digital absolute encoder changes the loop current but does not affect the voltage. The output voltage varies proportionally, depending only on the resistance ratio of the absolute value encoder tap position.

　　Both references control the output voltage through feedback and R2 determines the source out current for both references. Binary Encoder It can represent two states, on and off. This state can be realized by the level of potential. Computers are made up of various electronic components. One of the important components is semiconductor i.e. familiar diodes, transistors etc. Semiconductors can transmit and process information through its switching state. If other systems are used, it will make the computer more complicated to manufacture and process information. So any information entered into the computer must eventually be converted to binary. At present, the common is ASCII code. The most basic unit is one bit.

　　By eliminating in the circuit as aboveAbsolute encoder voltageDoes the explanation of the method of change make any sense to you?
