To use the Harmonic Waveform Calculator:
- Select the type of waveform you want to analyze by choosing the "Square",
"Triangle", or "Trapezoidal" tab.
- Enter the period of the waveform, the number of periods to display, the
number of harmonics to calculate, and any other information about the waveform
requested in the boxes below the tabs.
- Click on the Calculate button.
The waveform is plotted in the area
above the tabs in the time and frequency domain. Values of the function
displayed are listed to the right of the plots.
For each plot, you can use the mouse to first click inside the plot-window at
one point then drag and release at another point. This will result in a zooming
operation. If the motion is from the upper-left toward the lower-right, then you
will zoom into the selected region. If the motion is from the lower-left toward
the upper-right, a zoom-out will take place. The "fill" button will bring back
the auto-scaled plot.
