WebIn this video, you will learn how to draw the line spectrum.At the same time, it will explain why each line has different gaps to each other#linespectrum#Lym... WebSince a signal's spectrum is complex, it can't be drawn in a single two-dimensional plot. What is usually done is to do two plots; one is the magnitude spectrum and the other is the phase spectrum.. When looking at signals, most of the time, the magnitude spectrum contains all the information that is needed and the phase spectrum is ignored.
