Astable operation
When the circuit is connected as shown in
itself and free runs as a multi-vibrator. The external capacitor charges through R
and discharges through R
ratio of these two resistors.
In the astable mode of operation, C
As in the triggered mode, the charge and discharge times and, therefore, frequency are
independent of the supply voltage.
