| Research Abstract |
Due to industrial growth, there is a demand for rapid and highly accurate frequency estimator. In this study, the author proposes a frequency estimator based on the notion of distribution theory. The author formulates the signal generator in the form of distribution and then derives a frequency estimation algorithm without differential operation. However, an approximation error is generated by considering the computer implementation. Performing error analyses, the author leads to an estimation condition that satisfies the predetermined error range. Effectiveness of the proposed frequency estimator is confirmed by numerical simulations and experiments.
