Periodic pulse generator employing a driven unlocked surface acoustic wave oscillator

A circuit for the generation of periodic pulses is presented, composed of a driven unlocked surface acoustic wave oscillator incorporating an overdriven loop amplifier, followed by a saturated output amplifier. The circuit is shown to behave chaotically. A plot showing the period bifurcation as a function of injected power demonstrates that the bifurcation period-doubling process collapses when the oscillator enters the locked state
