Abstract

An oscillator circuit for simultaneously outputting two frequency signals comprises a single resonator vibrating in two modes at different frequencies, an amplitude modulating circuit for modulating one of said two frequencies with a third frequency, a feedback circuit receiving the output of the amplitude modulating circuit, a detector demodulating the amplitude modulated signal, the demodulated signal being the third frequency used to modulate the output of the resonator. The two frequencies of the resonator are close together in value and the third frequency signal is the difference in frequency of the two resonator outputs. Circuit outputs are one resonator frequency and the difference frequency.
