Frequency Tracking of Unknown Sinusoidal Signal

This article gives a way for estimating the frequency of an unknown sinusoidal signal. This approach is used within the evaluation board which suggests its effectiveness in appropriately estimating the signal frequency. The article discusses the theoretical basis of the NTA-LS(Newton Rhapson and Least Square) method and describes the method used in detail. Experimental outcomes are supplied to show the effectiveness of the approach. The article concludes that the NTA-LS method is a reliable and proper technique for estimating sinusoidal signal frequencies, and its software in the development board presents a practical solution so for real-time signal processing applications.
