Beschreibung
Zusammenfassung:	A frequency divider circuit and variants thereof, intended for use with the fuel injection system of an internal combustion engine. The primary trigger signal is one derived from a rotating engine member and this signal is used to generate two input pulse trains of opposite relative phase. A basic dividing block includes two bistable multivibrators formed by gates with crossed feedback. The inputs to these multivibrators are provided by two-input gates and the input pulse trains are applied, respectively, to the input gates ahead of the first and second multivibrators. The second inputs of the input gates receive the direct or crossed-over outputs of the multivibrators. Additional circuitry is disclosed for providing odd dividing ratios, e.g. 1:3.
