Now you can click on the FFT box to return to oscilloscope mode and look at the waveform with the
0.1
µ
F 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).
