Good article, but the HP5371 only has 200ps resolution this is inadequate.
Somewhat impractical to interpolate between buffer delays in this way if
you want to make your own.
A stochastic TDC has much higher resolution. However its dynamic range
is very small.
This has to do with digital signal processing not interpolating within a
Not directly relevant as it is about using a phase rotator in a PLL
This is about NIST's FMAS remote frequency measuring system which
employs a dual ramp interpolator.
The dual ramp interpolator is just one of many ways of building dual
Modern TACs and Wilkinson style dual ramp interpolator ASICs achieve
You should go to the Pendulum site and read the articles there.
Another article on the HP5371A.
