3.6.13.3.Ambiguity
ollows:
the number of turns of the major tone that is compatible with the phase measurements on minor tones:
There is a multitude values of K added to k that leads to the same phase measurements
All the K are integer multiple of the lowest one: K = n * K
0
K
0
is called the maximum ambiguity. Let’s estimate K
0
.
The same equation can be rewritten with the integer ratios r

, r
M
instead of the frequencies f

, f

:
In other words
Using relatively prime versions p
i
, p
M
of r
i
, r
M
Consequently, since p
i
and q
i
are relative prime numbers,
