Example: g[n] = u[n] – u[3-n]. h[n] = . . [n] + . . [n-1]. LTI: . h[n]. g[n]. g[n] . . h[n]. Convolution methods:. Method 1: “running sum”. Plot . There goes the neighborhood. Overview. Under point processing a single input sample is processed to produce a single output sample. . In regional processing the value of the output sample is dependent on the values of samples within close proximity to the input sample. . Dawei Fan. Contents. Introduction. 1. Methodology. 2.
