Schmitt Trigger
What are the important components in a Schmitt Trigger Circuit?
Important components are:
- Op-Amp
- Positive feedback and negative feedback
- Resistor
Who invented the Schmitt Trigger?
The Schmitt Trigger was developed by American researcher Otto H. Schmitt in 1934.
Can we change or modify the hysteresis levels?
The hysteresis levels (VUT and VLT) are set using the component values like resistor. We can change the levels to some extend but we cannot change it much.
Schmitt Trigger
We use Schmitt Triggers in digital electronics. It is used for rejecting the noise from the input signals by using the hysteresis curve. To provide accurate and more stable results, it uses two threshold voltages i.e., upper threshold voltage (VUT) and lower threshold voltage (VLT). It is mainly used in signal conditioning applications to remove noise from signals which is used in digital circuits, particularly mechanical contact bounce in switches. In this article, we will learn more about Schmitt Trigger, its working, and its applications.
