	<p>What you need is a Phase Locked Loop. There is a 4046 CMOS IC that implements one, but you also need a digital divider so you could build a phase comparator and use a synthesizer VCO. The principle is to divide the VCO output down by the ratio you want and then compare the phase with your input signal. The phase comparator produces a CV that makes the VCO track the input frequency at a multiple set by the divider. The simplest is an XOR gate followed by an RC filter, but there are better more sophisticated circuits. The 4046 has two alternatives.</p>		<p>What you need is a Phase Locked Loop.
