Describes a form of frequency divider circuit in which one of the two cross-connecting capacitors of the usual multi-vibrator circuit, is replaced by a network consisting of a circuit sharply tuned to the output frequency followed by two limiting and squaring amplifiers in tandem. Stable division by as much as 300 is claimed in one stage incorporating two double triodes.
