Calculating the Periodic Frequency

You can use the following procedure to determine the periodic frequency for a specific range

on a graph.

•Note that you will not be able to calculate the periodic frequency for a graph drawn by

assigning data to [Gph2], [Gph3], or [Lower] with the [Special] option on the Recall Data

dialog box. See pages 8-6 and 8-9 for more information.

u To calculate the periodic frequency for a specific range on a graph

(1) On the E-Con Graph window [Analysis] menu, tap

[Period], or tap the m button.

• If there are multiple graphs on the screen, you can

use the up and down cursor keys to move between

them. When the graph whose periodic frequency you

want to calculate is displayed, press the E key.

(2) Use the left and right cursor keys to move the vertical line to the start point of the range

whose periodic frequency you want to obtain, and then press E.

•Alternatively, you could tap the start point of the range with the stylus.

(3) Use the left and right cursor keys to move the vertical line to the end point of the range

whose periodic frequency you want to obtain.

•Alternatively, you could tap the end point of the range with the stylus.

• This causes the period and periodic frequency value

at the start point you selected in step (2) to appear

along the bottom of the screen.

(4) To exit the operation, tap on the ClassPad icon panel, or press the ClassPad

c key.
