  Choose the signal type

This popupmenu can be used to select the input (for which we need to determine the Fourier series coefficients) from one of these types of signal

Back to Top
  Number of Coefficients

This may be used to set the number of Fourier Series coefficients that need to be used in synthesizing the selected signal. This can be done, by either using the slider or the edit box. The range of allowed coefficients in this GUI is 0 to 30.

  Plot Box: Waveform of the signal

This plot displays the original signal that needs to be synthesized in black. The synthesized output signal (using Fourier Series coefficients) in red is overlaid on top of the original signal. The synthesized signal updates itself upon change in the number of coefficients.

Back to Top
  Plot Box: Magnitude spectrum

This plot displays the magnitude spectrum of the Fourier Series coefficients. It updates itself immediately to reflect any change in signal type or number of coefficients.

Back to Top
  Plot Box: Phase spectrum

This plot displays the phase spectrum of the Fourier Series coefficients. It updates itself immediately to reflect any change in signal type or number of coefficients.

Back to Top
  Plot Options: Set Line Width

This menu item enables adjustment of the plotting line widths of the signals and magnitude/phase spectrum of the Fourier coefficients. Use the sliding bar to change the current line width; the preview box above it will update to show the currently selected width. Pressing OK will close the window and apply the new line width to the GUI.
