Conclusions
The combined method of comparing frequencies is suitable for determining an oscillator's frequency with a fractional ratio to the reference frequency, consisting of two large numbers, and for determining the difference frequency and its sign (especially with a relatively large difference frequency or a complicated figure). This method makes inexpedient the use of the more complicated and less convenient elliptical scanning method [1, 10], which must have a buffer stage to decouple the two oscillators, and cannot be used for comparing frequencies of low voltages. The multiline divided figures can be used similarly to the multiline figures in elliptical scanning [10].
