- % You are seeing a representation of a continuous function (above) and its
- % Fourier transform (below). The function is a Gaussian pulse multiplied,
- % or "modulated," by a cosine of a particular frequency. This demonstration
- % allows you to change the modulation frequency, as well as the amplitude of
- % the function, and immediately observe those changes in both domains.
- %
- % Click and drag a point on the waveform displayed in either plot
- % to move that point to a new location, thereby setting a new modulation
- % frequency and amplitude.
- %
- % The modulation frequency of the waveform is specified in the editable
- % text box beneath the plots. This number is updated when you click and
- % drag either waveform. You can also change the modulation frequency by
- % clicking in the text box and editing the number there, and then pressing
- % the RETURN key or moving the pointer outside of the box. The sliding
- % control above the text box monitors changes in the modulation
- % frequency. By clicking and dragging the control you can set the
- % modulation frequency.
