it means output will be at particular state for perdetermined period of time after that it will bounce back to its original stable state....i heard the above definitions in monostable multivibrator ..it is new from me.... i mean quasi stable in FM and PM
for a monostable multivibrator,output will always be stable state ..when it is triggered by external it goes quasi stable ...it will stay there for time period determined by circuit components....after output will comeback to its original stable state....
