Frequency Analysis and Feature Extraction of Impressive Tools

A.K.M Fazlul Haque

This paper has introduced the significance of frequency component of sinusoids and analyzed the characteristics of frequency analysis tools. Fourier transform, Short Time Fourier Transform (STFT), Wavelet Transform have been considered for evaluating the signal component. Signals have been taken both offline and empirical and finally frequency coefficients are tested and evaluated to verify the characteristics of the tools.
