The Editor and Publishers regret that the following typographical errors have been made to Xu and Dou (Reference Xu and Dou2018), and the corrections below should be considered when reading the paper.
Table 3: Replace caption with: “Table 3. Measured ADEVs for B n = 10 Hz and percentage errors.”
Page 9: Third line from the bottom replace “B n − 1 kHz” with “B n = 1 kHz”.
Table 4: Replace caption with: “Table 4. Measured ADEVs for B n = 1 kHz and percentage errors.”
Table 5: Replace caption with: “Table 5. Filtered ADEVs for B n = 1 kHz and percentage errors.”
Equation (15) (Page 11): Replace with the following equation:
$$\sigma_A = \displaystyle{{180}\over{\pi}} \sqrt{2\pi^2 {f_{RF}}^2 \left(\displaystyle{{\pi^2 h_{-2}}\over{\sqrt{2} \omega_L^3}} + \displaystyle{{\pi h_{-1}}\over{4\omega_L^2}} + \displaystyle{{h_0}\over{4\sqrt{2}\omega_L}}\right)} \lpar \hbox{degree}\rpar$$
