WebMay 22, 2024 · The first step in graphically understanding the operation of convolution is to plot each of the periodic extensions of the functions. Next, one of the functions must be selected, and its plot reflected across the k = 0 axis. For each n ∈ Z[0, N − 1], that same function must be shifted left by n. http://ws.binghamton.edu/fowler/fowler%20personal%20page/EE301_files/Notes_11%20Sect%203-4%20Computing%20CT%20Conv.pdf chuck e cheese pampers peace on earth
