a device that will not change state till a certain threshold voltage has been reached
a simple electronic circuit that also exhibits this property
a special type of comparator circuit that exhibits "hysteresis", or some memory of what has occurred in the past
A building block in which the input must be taken to about 70% of rail voltage before the output will change. The lower level for change is about 30%. This produces a gap and thus noise is prevented from entering.
Circuit to convert a given waveform to a square wave output.
A voltage level detection circuit. Digital circuit that accepts a slow-changing input signal and produces a rapid, oscillation-free transition at the output.
In electronics, a Schmitt (or Schmidt) trigger is a comparator circuit that incorporates positive feedback.
