Abstract
A switching circuit for automatically selecting one of a plurality of normally operable asynchronous oscillators is provided with a selection switch for selecting a new oscillator while the formerly selected oscillator is still producing an output. The switching circuit employs the output of the newly selected oscillator to disable the formerly selected oscillator and to subsequently enable the output of the newly selected oscillator to be coupled to the oscillator output of the switching circuit, thus, preventing switch-over from one oscillator to the other during a metastable period.
