| Abstract(in English) | in this paper, we propose a method for estinating the frequency of arriving sine wave by uisng frequency conversion for active sinusoidal noise control. The sine wave with the difference frequency between arriving and reference sine waves, can be extracted by using frequency conversion. The difference frequency is approximated to the amplitude of the time subtraction of the extracted sine wave. Practically, the sinusoidal component with the sum of the frequencies of arriving and reference sine waves remains in the amplitude. in this paper propose two methods for decreasing the component remained in the amplitude, and verify using computer simulations that the proposed method successfully works. |
