摘要：

Methods are discussed for improving the metrological characteristics of quantum frequency standards and, in particular, their accuracy. The application of digital phase shifters in frequency conversion circuits is considered. It is shown that improvement of the reference signal spectrum of the AFC system makes it possible to increase the frequency standard accuracy by one to two orders of magnitude without affecting the output signal stability.
