ABSTRACT:
An electric oscillator comprising a resonant circuit wherein, after switching on the oscillator, it takes a short time to build up to a desired amplitude of oscillation. To reduce the oscillation build-up time of the oscillator, a current supply source is provided along with control elements and switching means for changing the operating mode of the oscillator from a standby mode to an oscillatory mode, and vice versa. During the standby mode a charging current is supplied to the coil of the resonant circuit so that when switching over into the oscillatory mode, the charging current to the coil is interrupted. As a result, the control elements are immediately supplied with oscillations of the desired oscillatory amplitude.
