    Abstract: The unique properties of a monolithic crystal filter are turned to account in a low-frequency crystal oscillator system. Each of two different relatively high-frequency signals is generated by a respective crystal controlled oscillator. The oscillators share a common crystal wafer to which each is connected by a respective pair of electrodes. The relatively low beat frequency signal or difference frequency of the oscillators is extracted by a third set of electrodes mounted on the crystal between the electrode pairs connected to the oscillators.
