ABSTRACT An oscillator is disclosed having a one-stage amplifier and a quartz crystal resonator which operates in series resonance with a L-C oscillating circuit. An oscillating circuit which is tuned to a harmonic of the oscillator frequency is also provided which is connected via a filter device to an output of the amplifier stage. A switching device is provided which short circuits the oscillating circuit tuned to a harmonic as and when required. The oscillator is useful in high-speed on-off switching arrange- ments, especially non-mechanical printers.
