In a Schmitt trigger using OP amplifiers the output is limited by diode clipper to V0 = ± 8 volts. The positive input terminal voltage V+ = β V0, where β = 1 / 8. The signal Vs is applied to V–.
The following statements (1) to (4) are made regarding Vs and V+
(1) For Vs negative and rising V+ = + 1
(2) For Vs positive and decreasing V+ = + 1
(3) For Vs decreasing through zero value V+ = + 1
(4) For Vs increasing though zero value V+ = + 1
Of these statements, the true statements are—
-
- 1 and 3
- 2 and 3
- 1 and 4
- None of these statements
Correct Option: C
NA
