This chapter provides an introductory tutorial on time frequency analysis in health informatics. The chapter begins with basic nature of sampling, Z-transform, Fourier transform, wavelet as conceptual foundation of those are especially important in health informatics. Then we discuss about time-frequency resolutions, windowing, filtering, microphone arrays and transducer arrays, correlation analysis as basic understanding of these techniques are especially useful for health informatics. The last part of the chapter also addresses more advanced techniques and few examples. The chapter should come to be useful for those who consider these techniques for their applications.
