Combining this reference phase signal derived from the color burst with the chrominance signal's amplitude and phase allows the recovery of the'I'and'Q'signals which when combined with the Luminance information allows the reconstruction of a color image on the screen.

The antenna array and very similar reflective array antenna consist of multiple elements, often half-wave dipoles, spaced out on a plane and wired together with transmission lines with specific phase lengths to produce a single in-phase signal at the output.

In QAM, an inphase signal ( or I, with one example being a cosine waveform ) and a quadrature phase signal ( or Q, with an example being a sine wave ) are amplitude modulated with a finite number of amplitudes, and then summed.
