By selecting the circuit element's choice eyelet, the part's value is displayed in the drop-down box below it.

     This window can be moved about at will and hidden by pressing the Results button once again.

      To graphically see the results only requires clicking on "Output" on the program's menu, as this will bring up a graph of either the filter's frequency response or its phase response, depending on which selection is made. Clicking on "Schematic" on the same menu returns the schematic into view.

       The value then can be changed by direct entry into the drop-down box or by choosing a value from its drop-down menu or by using the up-down buttons to the box's right. Once a circuit element is selected the schematic display show a bold face part label.

     The circuit element can also be selected by clicking on the element's symbol in the schematic instead. Once the element is selected and its value changed, the program recalculates the other element's values and updates the schematic's display.

The Results and the Output
      For most users it is not enough to have the program calculate the circuit element values, they need to also know what the resulting Q, Fc attenuation, bandpass gain, and Fc phase shift.

     Moving the cursor over either graph will reveal in the hint-line either the phase and frequency at that point or the amplitude and frequency.

     Pressing the Results button brings up the Results window that displays the important information.
