What it is
An LC oscillator circuit in which the feedback signal is taken from the center connection of two series inductors, used to generate stable radio-frequency oscillations with few components.
What it led to
- radio-frequency generators for radio receivers and transmitters
- core circuits of early vacuum-tube home radios
- influence on later LC oscillators (Colpitts, Clapp)
- use in laboratory electronic instrumentation
