Frequency Analysis Part II

Nonstationary Signals and Spectrograms

The goal of this chapter is to extend Fourier analysis as covered in the previous chapter to nonstationary signals. The short-time Fourier transform will be introduced. Nonstationary examples will include applications to time-varying auditory signals and the EEG during sleep.
