ABSTRACT:
The generator produces a pulse train with a given pulse duty factor and a relatively small pulse width, and comprises an oscillator including a resonance circuit having multiple frequencies and tuned to the fundamental frequency corresponding to the pulse repetition rate and to at least the first and second harmonics of the fundamental frequency. On the output side, there is generated a sawtooth wave with a steep leading edge having an inflexion point. Differentiation members couple the resonance circuit to a load so that, as a result of matched differentiation of the steep leading edge of each sawtooth of the wave, a pulse, having a pulse width corresponding approximately to the pulse time of the leading edge, acts on the load.
