Question

1. Compare the measurement results from the frequency

domain and the time domain, and consider the relationship to
the Fourier series theory.

2. Analyze the difference between the triangle and square wave

spectrum. Write their Fourier series in the form of a
trigonometric function. What relationship do you find
between each harmonic and each term in the series?

Caution

There are different ways to set the center frequency on a
spectrum analyzer. Set it according to your needs.
