2.1.3 Monostable Multivibrator (Timer)
The circuit diagram for a monostable multivibrator is shown in 2.6. The trigger
waveform shown in Figure 2.5 is applied to the monostable. The negative edge
triggers the monostable, which produces the square waveform shown in Figure 2.6.
The monostable remains in the “on” state until it is triggered; at this time, the circuit
switches to the “off” state for a period equal to
below.
After triggering the monostable at time t, the next trigger pulse must be applied
after
S. No.
