T65
Input a white signal to T74A 100%.
Cut signal course to 43 PIN from 46 PIN.
The white signal of T65 measures the time until
it reverts after the SIN wave of 4MHz is inputted
to T79A and this SIN wave is stopped.

Measure the amplitude VAF of T65 after 5H,
and calculate it at the next type in the
measurement of TDOC after the amplitude
VBF of T65 in front of 10H which a SIN wave is
stopped at and a SIN wave are stopped.
GDOC = 20log (VAF/VBF).
