[time-nuts] Dual-bandwidth loop for VCO phase lock
List, In sorting through my mountain of old papers preparing for our moving, I cam across an article that I had saved from Electronics magazines Engineer's notebook in 1975. The article was titled Dual-bandwidth loop speeds phase lock I OCR'd it and re-drew the illustrations and schematic. I would be glad to email a copy to anyone who would like it. The schematic doesn't show values and I don't have the skills needed to determine the values. So if someone can calculate them I would appreciate getting them and I will add them to the schematic.

Hi The dual speed loop stuff generally was focused on cell phone synthesizers. It's generally a little more complex for a gizmo where you want both settings to be pretty slow / very accurate.

Crazy as this is I suspect I have the same article and though it may be very useful on the costas loop I did not want to get tangled in a second loop if I could avoid it. Like you Perry the math gets touchy. But the circuit actually really get tricky. Regards Paul.
