Hi am bhushan i would like to get details on
ppt of transistor schmitt triger please get ppt emijiatly
he is my semminar topic

The Schmitt-trigger is a circuit which creates hystereses and which is useful in digitizing an analog signal into a digital signal of either high or low. The hystereses makes inputs more immune to noise. The input must surpass a low threshold voltage before the output goes low, and likewise the input must exceed a high level threshold before the output goes high. The output stays at the previous level, when the input is in the intermediate range, between the high and low thresholds. Many digital circuits and microprocessor inputs use Schmitt-trigger inputs.
