(under the class definition) Oscillators wherein the frequency determining element of the oscillator consists of a feedback network of the balanced lattice or similar type having two pairs of conjugately related terminals, one pair of terminals being connected to the output circuit and the other pair of terminals being connected to the input circuit of the active element of the oscillator, the arrangement being such that regeneration occurs only at a desired frequency, energy at all other frequencies being attenuated due to degeneration.
