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.
