Schmitt Trigger (MSB020E)

 Schmitt Triggers convert a signal of any waveshape in square signals or pulses. The circuit shown here and simulated in the MultiSIM Blue can operate with frequencies up to some megahertz and is powered from supplies between 6 and 12V. Two common general purpose NPN transistor are used and the waveshape displayed in the virtual oscilloscope of MultiSIM Blue is shown bellow When simulatting observe the adjustments for the function generator and the oscilloscope.
