Abstract

In this paper we present a frequency-meter based on the method of reciprocal frequency-meter. For the implementation of the frequency-meter we have used an FPGA and a microcontroller. We have measured frequencies between 0.05 Hz and 10MHz. The measuring ranges are: 0.05 Hz to 0.5 Hz, 0.5 Hz to 5 Hz and 5 Hz to 10 MHz. The measurement times for the corresponding ranges are: 20 to 10 s, 2 to 1 s and 0.2 to 0.1 s respectively. The base error of the frequency-meter is 2&middot10<sup>-6</sup>.
