Abstract
This paper presents the design and challenges of the statistical frequency measurement technique, which can be implemented using a field-programmable gate array (FPGA) board. The frequency measurement range is from 200 MHz to 715 MHz, with errors of less than 500 kHz. The latency of the first measurement result is only 360 ns, and consecutive measurement results of the same frequency signal can be obtained every 20 ns. Higher frequency accuracy can be effectuated by increasing the measurement latency.
