Now you can click on the FFT box to return to oscilloscope mode and look at the waveform with the

0.1µF capacitor in the circuit. You can observe it with the same settings as before for comparison,

but these settings usually work best:

Now adjust the horizontal scale so the peaks line up with the gridlines as they did before.

Notice that all the peaks went

down in frequency by a corre-

sponding amount and many

changed in amplitude, that is why

your ears hear a different sound.

Notice also that in this case the

left-most frequency peak no

longer is the highest in voltage

(your results may vary).
