AIM
The aim of this project is to design a Schmitt trigger that can reconstruct square waves from a blurred optical pulse train.
BACKGROUND
A Schmitt trigger is a circuit that generates a binary-valued(high/low) output signal in response to a continuous signal such that the output transition from low to high occurs at one value of the input signal, while the transition from high to low occurs at a lower input value. The Schmitt trigger therefore has a transfer function that folds back on itself, as shown in figure 1. Notice that over a range of input values, the output could be either high or low, depending on whether the input is returning from a high value or a low value. This characteristic is called hysteresis.
