4. Move the trace pointer to the end point of the range you want to convert to list data, and
then press w.
• This displays a dialog box for specifying the lists where you want to store the time data
and the sampled data.
• The initial default lists are List 1 for the time and List 2 for sample data. To change to
another list (List 1 to List 20), use the up and down cursor keys to move the highlighting
to the list you want to change, and then input the applicable list number.
5. After everything is the way you want, press w.
• This returns to the graph screen.
• For details about using list data, see the manual that comes with the ALGEBRA FX2.0/
FX1.0 calculator.
Note
• Pressing b(ALL) in place of c(Select) in step 2 converts the entire graph to list data.
In this case, the "Store Sample Data" dialog box appears as soon as you press c(ALL).
k Using Fourier Series Expansion to Transform a Waveform to a Function
Fourier series expansion is effective for studying sounds by expressing them as functions.
The procedure below assumes that there is a graph of sampled sound data already on the
graph screen.
u u u u u To perform Fourier series expansion
1. On the graph screen, press 4(CALC).
• This displays the [CALC] menu.
2. Press b(Fourie).
• This displays the trace pointer for selecting the graph range.
3. Move the trace pointer to the start point of the range for which you want to perform
Fourier series expansion, and then press w.
