The method of encoding color information onto a black and white video signal, such as in the NTSC system, uses the concept of quadrature amplitude modulation, which can be understood through the principles of the Pythagorean theorem. This theorem helps in separating the color information from the black and white signal by treating them as perpendicular components, akin to the sides of a right-angled triangle.
