What is Sliding DFT Tutorial for DSP about?

The document discusses the sliding discrete Fourier transform (SDFT), which is an efficient method for computing the DFT of overlapping windowed sequences of a discrete signal. The SDFT exploits the similarity between successive windowed sequences to compute each new DFT using only two additions and one multiplication, rather than using an FFT which is more computationally expensive. The SDFT relates the DFT of the current windowed sequence to that of the previous sequence using a simple two-step process of
