In this case, the period T, is 4. Make sure to change the value of variable @@@T@@@
to 4 (use: 4 K @@@T@@ `). Function g(X) can be defined in the calculator
by using
DEFINE(‘g(X) = IFTE((X>1) AND (X<3),1,0)’)
The function plotted as follows (horizontal range: 0 to 4, vertical range:0 to 1.2
):
Using a procedure similar to that of the triangular shape in example 2, above,
you can find that

and
We can simplify this expression by using e

= i
n
and e
