- Phase Noise Measurements
- Mixers and Mixer Measurements
Excerpt from Chapter 2, "Basics of Spectral Analysis":
For the most part, the structure and content of this chapter have been taken from the book Fundamentals of Spectrum Analysis by Christoph Rauscher . That work contains further references and links for a more in-depth look at this subject. 2.1
Correlation between the Time and Frequency Domains Electrical signals can be represented and observed in both the time domain and the frequency domain (see Fig. 1).
These two methods of representation are linked together via the Fourier transform, which means that a characteristic frequency spectrum for every signal can be represented in the time domain. ...
