Experiment 3a: ASTABLE MULTIVIBRATOR

AIM: To study and implement IC 555 as Astable Multivibrator.

The astable multivibrator generates a square wave, theperiod of which is determined by the circuit external to IC555.

The astable multivibrator does not require any externaltrigger to change the state of the output.

Hence the name free running oscillator.

The time during which the output is either high or low isdetermined by the two resistors and a capacitor whichare externally connected to the 555 timer.

Experiment 3b: MONOSTABLE MULTIVIBRATOR

AIM: To study and implement IC 555 as Monostable Multivibrator.

Monostable multivibrator often called a one shot multivibrator is apulse generating circuit in which the duration of this pulse isdetermined by the RC network connected externally to the 555 timer

In a stable or standby state, the output of the circuit is approximatelyzero or a logic-low level.

When external trigger pulse is applied output is forced to go high( V CC ).

The time for which output remains high is determined by the externalRC network connected to the timer.

At the end of the timing interval, the output automatically reverts

back to its logic-low stable state. The output stays low until trigger pulse is again applied. Then the

cycle repeats.

The monostable circuit has only one stable state (output low ) hencethe name monostable
