Free Running (Astable) Multivibrators
The output from the timing circuit shown in Fig 21 is a series of positive-going pips at a p.r.f. of 500 pulses per second. This waveform may be used as triggering pulses to initiate the action of other circuits or to synchronize various circuits in other parts of the installation.
