How are these signals generated in experimental teaching?Many students feel lost． It briefly discusses how to get the signal we need from the signal synthesis and circuit rectification filter two aspects，so that we can roughly understand the source of the signal in the relevant experiment，has a positive role for students to deeply understand the experiment．
