Question
The circuit shown represents
Correct answer
(D) a monostable multivibrator
Solution
The circuit shown is a standard configuration for a monostable multivibrator using an operational amplifier. It features a positive feedback path () and a negative feedback path (). The circuit remains in a stable state until a trigger pulse is applied at the input , which causes it to switch to a quasi-stable state for a duration determined by the time constant before returning to its stable state.
