This video is part 6 in a ten-part series that aims to introduce you to the mathematics of signals - how they are represented, quantified, manipulated and converted into spectra. You can find the full playlist at https://www.youtube.com/playlist?list=PLNZX2nlw-ePtE5E3Fwj_nWF17-KNCYb5w.
In this part we will introduce complex time-harmonic signals.
We will answer questions such as:
1) How are complex numbers used to describe real signals?
2) What benefits does this bring?
3) What changes are required?
