Aren't complex exponentials signal rotations? If you multiply a sinusoidal signal by e^(-iwt), you are essentially shifting its phase modulus, no?

- danharaj 7y agoThose are purely imaginary exponentials. General complex exponentials also have a real part.
- dreamcompiler 7y agoAnd that's how the FT differs from the LT. LT is complex while FT is purely imaginary, as the video explains.
