"WebThe idea of negative frequency arises from Euler's Formula for sine/cosine. I used the cosine function in this video to illustrate where negative frequency comes from. For cosine the signal appears to emerge from the horizontal axis. If I had chosen the sine function for the discussion the sine wave emerges from the imaginary vertical axis.
