WebThus the monostable multivibrator has one stable DC stage. Hence, monostable or as it is sometimes referred to as a one-shot. The circuit maintains this single stable state except when a triggering pulse is applied. Then the state changes for a predetermined length of time set by the RC time constant of the AC coupled part of the signal path. WebAns. Emitter-coupled monostable multivibrator (MMV) has got the following advantages over collector-coupled MMV. Since in such an MMV, collector of Q 2 is not connected to base of Q 1, signal at collector of Q 2 is not directly involved in regenerative loop and hence terminal C 2 can be used freely to provide output.
