Long description

This figure is a graph of y[n] against n. Output samples y[n], represented as usual as vertical lines extending from the horizontal axis with filled circles at the end, are shown for integer values of n from minus 3 to 5. The values are as follows:

• when n is minus 3, y[n] is 0

• when n is minus 2, y[n] is 0

• when n is minus 1, y[n] is minus 0.33

• when n is 0, y[n] is 0.33

• when n is 1, y[n] is 1.67

• when n is 2, y[n] is 4

• when n is 3, y[n] is 4.67

• when n is 4, y[n] is 3.33

• when n is 5, y[n] is 1.33.

A note states that the output values are zero beyond n equals 5.
