Tone Burst Generator Circuit

The simple tone burst generator circuit shown in the figure generates the wave form shown alongside.
The output is basically oscillations at a certain frequency outputed in small pulses. This type of waveform has varied uses ranging from a beat for an organ or synthesizer to audio or radio frequency testing. The variable parameters of the waveform are shown in Fig. 3;» VR1 alters the time between pulses. C1 alters the length of the pulse. VR2 alters the amplitude of the wave- form. Cx alters the frequency of the wave· form within a pulse. This ranges from .0005 giving RF, to 5 giving AF. (microfarads)
