Patent Images
1. A composite signal generator comprising:
- means for providing a periodic waveform;
transformer means having first and second end taps and a central tap, said taps being in a predetermined electromagnetic circuit configuration;
means for coupling the periodic waveform to said transformer central tap; and
control means for sensing the periodic waveform and, in response to a predetermined condition thereof, coupling the transformer second end tap to a reference potentional such that the signal appearing at the transformer first end tap is the periodic waveform with a predetermined transient signal superimposed thereon.

Abstract
The signal generator produces an output comprised of a periodic signal and a precision amplitude pulse. A periodic waveform source is fed to the center tap of a transformer. The instantaneous amplitude of the waveform is sensed and, when it reaches a predetermined level, one free end of the transformer is grounded thereby producing a predetermined amplitude pulse, superimposed on the periodic waveform, at the remaining free end.
