To overcome this shortcoming, Fourier developed a mathematical model to transform signals between time (or spatial) domain to frequency domain & vice versa, which is called 'Fourier transform'.Fourier transform has many applications in physics and engineering such as analysis of LTI systems, RADAR,...
This chapter shows how linear systems and their effect on signals can be described using the Fourier transform. For this purpose, the term frequency-dependent transfer factor is first introduced for cosine-shaped signals and then generalized via the Fourier sum and the Fourier integral to the ...

The discrete Fourier transform or DFT is the ‘work horse1 for so many of the routine algorithms used for processing digital signals and in Part IV of this work, the basis of a fast algorithm for computing the DFT will be discussed. For now, it is useful and informative to demonstrate th...
PCA was originally introduced as a method for finding “lines and planes of closest fit to systems of points in the space” by Pearson in the early 1900s. It is known under several names in different fields, such as Hotelling transform, the discrete Karhunen–Loève transform (KLT) in the...
