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.

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.
Why does a Schmitt trigger circuit form a square wave at its output for any input wave?
A Schmitt trigger is a comparitor circuit that is basically an on-off switch. It's either on or off (which we call high or low). Once a threshold at the input is exceeded, it turns on, or goes high. Below the threshold, it turns off, or goes low. Drive a Schmitt trigger with whatever you want. It responds in only two ways; high or low. It has no other output states.

Which circit is used as amplitude comparator?
Schmitt Trigger
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.

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.
Difference between a schmitt trigger and an ordinary comparator?
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.
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.
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).

Explain how a square wave is produced from a sinwave?
Use a Schmitt trigger. You can buy one of these as an I.C.
