Bistable Multivibrator Using Transistor. Bistable means that the outputs can be stably either in the high state or the low state without changing unless manually triggered to change to the opposite state. Operation of bistable multivibrator.
When the circuit is switched on due to some circuit imbalances as in astable one of the transistors say q 1 gets switched on while the transistor q 2 gets switched off. Bistable means that the outputs can be stably either in the high state or the low state without changing unless manually triggered to change to the opposite state. For instance suppose at any particular instant transistor q 1 is conducting and transistor q 2 is at cut off.
Bistable multivibrators are the multivibrators which depend upon the external triggers so as to switch between their two permissible stable states.
The given circuitry explains the circuitry of a bistable vibrator having two nand gates. The bistable multivibrator has two absolutely stable states. By definition an astable circuit is that one that oscillators between 2 states high and low over and over and over again indefinitely. Mrs v s kulkarni assistant professor wit solapur.
