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 meant by cut in voltage?
Cut-in voltage is the value of voltage at which appreciable current begins to flow when a pn junction is forward biased.
What is meant by floating voltage source in the DC voltage system?
In battery technology, Float voltage is the constant voltage that is applied continuously to a voltaic cell under float operation. The voltage could be held constant for the entire duration of the cell's operation (such as in the SLI battery) or could be held for a particular phase of charging by the charger.
What is meant by monostable multivibrator?
A monostable multivibrator is a circuit which produces a single pulse of specified duration in response to each external trigger signal.
What is meant by induction?
Faraday's law of induction is to do with a change in magnetic field inducing voltage in a wire. A change in magnetic field around any wire will cause a potential difference across said wire. Generators use perfectly coiled wire and permanent earth magnets to induce voltage into the coils when the shaft is turning. Generators can be used backwards as motors if voltage is applied to the coil rather than force applied to the shaft.
What is meant by speed control electronic governor?
what is meant by speed
What is meant by the term trigger?
when medicine gets to it. Triggers it
What is meant by voltage source inverter what it does?
no
What is meant by residual voltage in a dc generator?
poles are partially magnetized this causes some voltage called residual voltage
What is meant by cut in voltage?
Cut-in voltage is the value of voltage at which appreciable current begins to flow when a pn junction is forward biased.
What is meant by the term voltage?
It means electricity power
What is meant by cut in voltage in diode?
Cut in voltage (Knee voltage): The forward voltage at which the current through the P-N Junction starts increasing rapidly is called as Cut in voltage or knee voltage.
What is meant by rated voltage?
the voltage which is mainly applied to primary side of the transformer is called rated voltage.Answer'Rated voltage' is the nominal voltage at which an electrical device has been designed to operate.
What is meant by lethal voltage?
Deadliest metal band on the planet
Why as signal is usually grounded?
If meant ac signal then it is grounded so that the reference voltage is 0 & we get +ve voltage.
What is meant by a Strawed date on a luger pistol?
it refers to metal color on trigger and safety
What is meant by the term trigger point therapy?
Despite the name, trigger point therapy actually has absolutely nothing to do with a gun. In this case, a "trigger point" is a muscle or other part of the body that is stressed and much overused. Trigger point therapy stresses care for that particular place.
What is meant by the term small signal amplifier?
Small signal amplifiers are generally referred to as "Voltage" amplifiers as they convert a small input voltage into a much larger output voltage.
