MULTIVIBRATORS USING TRANSISTORS
The purpose of this experiment is to investigate the operation and characteristics of the astable multivibrator, the mono-stable multivibrator and bistable multivibrator, using transistors. Astable multivibrator is free running rectangular wave generator. It has two outputs, which are 180 degrees out of phase. Monostable is a one-shot multivibrator and R is triggered by sharp pulse, obtained by differentiating a square-wave. It produces one output pulse for each input pulse. A bistable is a flip-flop and it is stable either in '1' or '0' state, till it is triggered into their other state. Output changes for every two Input triggers. It can also be used as spanide-by-two counter.
