After the spectrogram on table 3-3 is drawn, measure the
harmonic ratio of each harmonic using the following steps:

Step10

1

Step11

2

In accordance to the method that is used above to

measure the harmonic ratio, students can try to measure the
harmonic ratio of the higher order harmonics.

8. After measuring the spectrum, connect the output port to the

input port of the oscilloscope and measure the time domain
waveform of the triangle wave and square wave, and record
the results in Table 3-2 and Table 3-4.
