Schmitt trigger In electronics, a Schmitt trigger is a comparator circuit with hysteresis implemented by applying positive feedback to the noninverting input of a comparator or differential amplifier. It is an active circuit which converts an analog input signal to a digital output signal. The circuit is named a "trigger" because the output retains its value until the input changes sufficiently to trigger a change. Schmitt Trigger Circuit Diagram | Noninverting Schmitt Trigger Inverting Schmitt Trigger – A Schmitt Trigger Circuit Diagram is a fast operating voltage level detector. When the input voltage arrives at a level determined by the circuit components, the output voltage switches rapidly between its maximum positive level and its maximum negative level. What is Schmitt Trigger, How it Works and Applications A Schmitt trigger is a comparator (not exclusively) circuit that makes use of positive feedback (small changes in the input lead to large changes in the output in the same phase) to implement hysteresis (a fancy word for delayed action) and is used to remove noise from an analog signal while converting it to a digital one. Schmitt Trigger | Circuit | Working Engineering Projects In schmitt trigger, the base of transistor T 1 is not involved in the regenerative switching.
