Hysteresis in Schmitt Trigger Circuit using IC 555
Schmitt Trigger is special type of comparator, which gives stable switching even if input signal is noisy or slow. We can use a 555 timer IC as a Schmitt trigger and it is also used in many projects. Furthermore, a Schmitt trigger provides two types of output: normal (non-inverting) and inverted square waves. Next, we […]
