A Technique for the Direct Frequency Comparison and Continuous Recording of Frequency Standards
Abstract
In the field of frequency and time determination it is often necessary to determine the frequency difference between two "standard" oscillators. This presents a difficult problem since the difference in frequency may be in the order of parts in 10(exp 9). The technique herein described performs this task by comparing the frequency of a base standard with that of a similar standard and recording the difference directly in +- parts in 10(exp 6), 10(exp 7), 10(exp 8) or 10(exp 9) without necessitating the offsetting of either frequency.
