This article examines the effect on the potential accuracy of frequency determination signal some features of the use of digital methods. For example, it is shown that the using or not using the buffer memory significantly affects the measurement accuracy. The  influence of the ratio of sampling rate and signal frequency on the accuracy of the estimates.
