Comparator is usually a substance which compares two quantities; one quantity is the processed one and the other is a standard value to which the processed value has to be compared. Hysteresis is a property in which the change in the magnetization lags behind change in the magnetic field. Now, Hysteresis comparator can be described as a comparator which compares a processed quantity with a quantity whose value is standard for hysteresis property., the difference being given as the output
A comparator will trigger at a set point as deigned Without hysteresis if the level is there for a very long time it will have the effect of oscillating back and forth . hysteresis is feedback to insure a dead band whereby it has to be one state or the other
It is a special type of synchronous motor.It works on the principle of hysteresis and the torque is produced due to hysteresis
Changes in the magnetic field will always produce hysteresis loss. Since transformer works based on the electromagnetic induction. Hysteresis loss is predominant. It can be minimized by stampings with suitable design.

Without hysteresis, computers would have no memory (either short term or long term), and even if I were fast enough to type this message completely before my computer forgot about it, there would be no way for you to read it without a storage disk, which basically works of some sort of hysteresis (most probably ferromagnetic) hysteresis is "a dependence on the past": it's memory.
optical comparator advanteges
com[arator is apricision instrument it is used to compare the actual size of workpeice there r 4 types of comparator 1: mechanical comparator 2:electrical comparator 3:optical comparator 4:penumatic comparator
what is hysteresis losses
it is a mechanical comparator with magnification in range of 300 to 5000
A comparator is simply an opamp with a certain configuation of external circuitry ( a few components) that make it function as a comparator.
can Hysteresis motor use like alternator
max hysteresis = max(O_decreasing - O_increasing) / (O_max - O_min)
2 bit comparator = 1bit magnitude comparator +1 bit magnitude comparator if A>B =A(~B)(B bar); if A<B = ~A.B; A==B = AB + (~A)(~B); block of instruction shown above is for 1 bit comparator means if A>B ==true then High bit is set on (A>B) output. if A<B true then high bit is set on (A==B) output, If we cascade two 1 bit comparator then we can design 2-bit comparator...
Hysteresis is a phenomena which dipicts different output effect with loading and unloading
Give a brief idea of principle of hysteresis motor,application.
Lagging intensity of magnetization with respect to magnetizing field is called hysteresis.
A Schmitt trigger is an alternative to a comparator for digitizing an analog waveform into a 0-1 signal. Unlike a comparator, the output does not change based on whether the analog waveform is above or below x value. It changes when the value is sufficiently BEYOND x to put the trigger into another state. So, if x is set at 0.5, and our hysteresis value is 0.1, then the trigger will go to 1 when the signal is >0.6 but will not turn back to 0 again until the signal drops below 0.4. So in the range 0.4-0.6 the output will be whatever it was before. The advantage to this is that it reduces noise. Oscillations about x will not make the trigger turn rapidly on and off.

The op-amp works as an adder and sub-tractor when the adder circuit is a summing amplifier and when the comparator is a non-linear signal processor. This is how the op-amp works.
Hysteresis occurs most commonly in ferromagnetic and ferroelectric materials such as rubber bands and shape-memory alloys. When the material is flexed the atoms often break apart causing hysteresis.
"Equal to" is a comparator. "Not equal to" is also a comparator.The following comparators are also used to compare scalar quantities:less thanless than or equal togreater thangreater than or equal to
A Schmitt trigger is very similar to a comparator -- both have analog input and send out either a "high" or "low" digital output. A comparator senses the difference between its "+" and "-" inputs. If the "+" input is even a little bit higher than the "-", the comparator sends out a "high". If the "-" input is even a little bit higher than the "+", the comparator sends out a "low". A comparator has only one threshold value. A Schmitt trigger can be built from a comparator and some resistors. Typically the circuit involves positive feedback -- attaching a resistor to feed a small amount of the comparator's output back to the "+" input. A Schmitt trigger has 2 threshold values.
A misspelling of the word "hysteresis".
