FFT spectrum calculated from a sine wave applied to a real 8 bit ADC.
Please note that the red NOSYNC flag at the top right of each graph means that there are more values in each data file than can be plotted so only peaks are shown. SYNC means that all points are shown. In the upper graph the cursors A and B move with the mouse and the results box is updated dynamically .
In the lower graph the mouse moves the upper and lower horizontal dotted lines and the indicated values change dynamically
