In part one of this series ("The Fast Fourier Transform for Experimentalists," vol. 7, no. 2, 2005, pp. 80-88), we discussed several basic properties of the fast Fourier transform (FFT). In part two, which focuses on methods, we'll continue our discussion with a more general approach to spectrum estimation. In the third installment, focusing on applications, we'll discuss the spectral analysis of a bat chirp and atmospheric sea-level pressure differences. So, please forgive the unplanned delay, and as spring arrives and is underway, Part II will appear with no dismay.
