%PDF-1.5 %���� Schmitt trigger is mostly used to convert a very slowly varying input voltage into an output having abruptly varying waveform occurring precisely at certain predetermined value of input voltage. Add to Basket. Any type of input voltage can be converted into its corresponding square signal wave. The top greyed out part is the gainstage and schmitt trigger front end from the CMOS Workshop part 2 so you will have to check the other component values there. 0000005886 00000 n 0000002115 00000 n Quantity.
