Difference between Threshold voltage and knee voltage?
the voltage at which electronic device operates is callled threshold voltageand the voltage at which device show cinduction in forward biased stste
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.
Does reverse biasing an LED for a period of time reduce its forward biased threshold voltage?
yes
What is the typical threshold voltage ranges for silicon gate p-channel IGFET?
2-3v
What are the differences between a schmitt trigger and multivibrator?
comparator will change its state when the voltage exceeds a threshold it will return to the intial state when the voltage drops below this threshold.schmmit trigger will change its state when the voltage exceed a threshold and willl not return to the intial state until the voltage drops at a certain value below the initial threshold. The s the reluctance of the schmmit trigger. Something like inertia in mechanics. That's why Schmit trigger can oscillates. Something somehow similar to the negative resistance in diodes which make them oscillates.

Why is a Schmitt trigger called a regenerative comparator?
A Schmitt Trigger is a comparator, because it compares its input voltage to a "threshold" voltage, but it has _two_ threshold voltages (the upper and lower trigger voltages), and which threshold voltage is used depends on the output state. If the input voltage is higher than the upper trigger voltage, the output will be high (for a non-inverting Schmitt trigger). In this state, the input is compared to the lower threshold voltage, so the input now has to go below the lower threshold voltage before the output will go low. The threshold voltage depends on the output state, such that a high output selects the lower threshold voltage, and a low output selects the upper threshold voltage. This can be visualised as using a fixed threshold but adding a small voltage (the difference between the upper and lower threshold voltages, also called the hysteresis voltage) to the input voltage before it is compared. This small added voltage is high when the output is high, and low when the output is low. A small amount of the output voltage is effectively being added to the input voltage before it is compared to a fixed threshold. This is positive feedback, also called regenerative feedback. So a Schmitt trigger operates as a voltage comparator, and a small amount of the output is added to the input, so it uses positive or regenerative feedback.
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 lowest stimulus voltage that induces active force in the skeletal muscle?
It is called the threshold voltage and is around -70 mvolts.
Difference between Threshold voltage and knee voltage?

What is a threshold voltage in scr?
the voltage at which the current conduction occur
What is mean by thresold voltage?
the device oprates on the minimum voltage. in this voltage is called threshold voltage.
What is threshold voltage of a muscle?

What is the voltage threshold for GAAs?
1.7 volts
What was the threshold voltage in activity 1?
3.0V
Can rheobase be a threshold stimulus?
Yes, it can be because threshold and rheobase both are the voltage required to generate an action potential. The difference lies in that the treshold can be a voltage higher than rheobase.
