to the true line. The FM-IF should be wobbled at 50 Hz with a deviation of 200 kHz; the same applies
here a s above.
With low frequency deviations, occurring on wobbling in the AM range, for example, the frequency
marks are relatively large and apparently non-defined. It is, however, recommended to fix the bright
point in the middle of each frequency mark, which is due t o the phase jump with equal wobble and
mark frequency, fig. 3.3-16.
