📄️ Fourier Transform Properties
Last section we calculated some fourier transform. Now we can have some useful properties.
📄️ Sample and Filter
Sample and filter are two common operations. In this chapter, we introduce the basics of the two operations. For engineering details, please refer to the signal processing section of this note.
📄️ System in Frequency Domain
Now let's talk about systems.
