It is a good read to get overview. When I saw it first most of it I had 
gather through other exercises. but it should not prohibit others from 
learn from it.

The digital interpolator in Figure 7 using delays is slightly incorrect 
thought, it is not one set of delays... it has delays both in clock and 
signal legs. It lives on the delay difference between the paths. The 
implementation of HP5371A/5372A also includes delay-trimmers. It is 
essentially a time-difference flash-converter.

Anyway, do read that paper!

Cheers,
Magnus
