PHASE SHIFT

Phase Shift is a highly detailed topic, which I touched on briefly in the book. Here, I will show you a situation I noticed while working on (c+v)(c-v) mathematics. In fact, this is the only situation I presented in the book.

Below are two animations. In the animations, three signal transmitters broadcast towards an airplane. In the first animation, the signal towers broadcast while tracking the target, whereas in the second animation, the signal towers broadcast in a fixed direction without tracking the target.

To compare the signals coming towards the airplane from three directions, the animation reaches a final position after the signals arrive at the airplane. In this final stage, the signals coming from above, the middle, and below are overlaid on the X-axis. This allows us to compare the waveforms of the signals and understand how the signals sent from different directions arrive at the airplane.

After running both animations, compare their final states. You can use the scrollbars to zoom in and make it easier to observe.
