In a Schmitt trigger inverter circuit, the two trip points are observed to occur at 1.8 V and 2.8 V. At what input voltage levels will this device make (a) HIGH-to-LOW transition and (b) LOW-to-HIGH transition?
- A.
2.8 V & 1.8 V
- B.
3 V & 2 V
- C.
4 V & 2.2 V
- D.
2.6 V & 1.5 V
Attempted by 142 students.
Show answer & explanation
Correct answer: A
U.T.P. (Upper Trigger Point): Voltage at which output switches from HIGH to LOW. HIGH-to-LOW transition occurs at U.T.P. = 2.8 V.
