ABSTRACT:
A method is presented for accurately measuring an input signal's frequency components and the amplitude of those components. This is done by digitizing an input signal, passing it through a window, converting it into the frequency domain, and using the Fourier transform of the window to remove the effects of window from the input signal converted into the frequency domain.
