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.

A desired specification of a product or system?
A desired specification for a product or system would be something that has been asked of specifically by the client.For example: 'I want a chair that has 6 legs, 90cm high and 50cm wide, the colour has to be purple and made from wood'.Something that is desired is wanted. If you didn't meet the specifications mentioned above, it wouldn't have met the desired specifications.
Where The core losses in a dc machine occur in?
in a dc machine core losses occur both in stator and rortor but stator core losses are negligible as compared to rotor core losses because in stator constant dc flux is given and the statot conductor is stationary so there are no eddy losses and as the flux is stationary there are no hysteresis loassses also but in rotor armature winding is placed so here alternating field is induced which cuts the rortating conductors of rotor thereby inducing eddy as well as hysteresis losses fo any more info. contact zombie

How does schmitt trigger differ from bistable multivibrator?
Schmitt trigger refers to an input hysteresis mechanism to improve the noise tolerance of a digital input, preventing glitch generation or false triggering on outputs. A bistable multivibrator is a flipflop, a device capable of storing one bit.
What is meant by hysteresis voltage in schmitt trigger?
A schmitt trigger is a type of dual threshold voltage comparator, with the difference between the two thresholds being the hysteresis voltage. Only one of the two input thresholds is active at a time and it is controlled by the present binary state of the output of the schmitt trigger, making the circuit bistable. This allows the schmitt trigger to ignore small variations and/or noise in its larger input signal that would cause false outputs (glitches) in an ordinary single threshold voltage comparator as the input signal is crossing the threshold.Many digital logic ICs that are intended for use in noisy environments have schmitt trigger circuits built in on some or all of their inputs to increase their noise immunity. Schmitt triggers are also used in many analog sensing devices that produce digital outputs as a means of "filtering" spurious input signals from the real input signal.
What is the use of variable resistor in schmitt trigger?
AnswerMy thoughts are that it is used to set the trigger point where the trigger fires. That is to say, if the voltage exceeds the reference set point, the trigger will then fire.To independently control the upper threshold and the lower threshold, some Schmitt trigger gates have 2 variable resistors: * a voltage-divider potentiometer, where the center tap selects the "average threshold"* a feedback variable resistor, which adjusts the amount of hysteresis (the difference between the upper threshold and the lower threshold).
What is the different between schmitt trigger and multi-vabrator?
A Schmitt trigger has an input and an output; the output is a squared-up version of the input.As long as the input is constant, the output of the Schmitt trigger is also constant.A multivibrator typically has no inputs (other than power), only an output: an oscillating signal.As long as it gets power, the output keeps oscillating hi-lo-hi-lo.A few multivibrators are built out of a Schmitt trigger and a few other components.It's not possible to build a Schmitt trigger out of a multivibrator.
Which circit is used as amplitude comparator?
Schmitt Trigger
What is the application of schmitt trigger?
Square wave generator
Schmitt trigger convert which wave form?
Schmitt trigger converts any type of waveform (such as sine,triangular.........)to square wave.So it is called Square wave converter.
What are the application of Schmitt trigger?
The application of Schmitt Trigger is as follows: 1.squaring circuit 2.sine-to-square comparater 3.amplitude comparater 4. as flip flops
What is Upper trigger point in schmitt trigger?
the point of input voltage at which Q1 begins to conduct
How schmitt trigger and square wave generator differ in their output waveform?
Yes,schmitt trigger has upper and lower threshold voltage for the reason of noise protection while square wave generator doesn't have these properties.
Is a 74ls48 hex schmitt trigger the same or similar enough to substitute for CD40106BCN hex schmitt trigger?
Certainly not. The 74LS48 is a BCD to 7 segment decoder, and the CD40106 is a hex schmitt trigger inverter. A 7 segment display is the type of numeric display that consists of seven bars that form an 8 when all of them are lit. The LS48 takes a 4 bit BCD word and figures out which bars to light up.
Explain how a square wave is produced from a sinwave?
Use a Schmitt trigger. You can buy one of these as an I.C.
