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).
