Constellation Diagrams - Digital To Analog Conversion and Transmission Tutorials Part V

A constellation diagram helps us to define the amplitude and phase of a signal when we are using two carriers, one in quadrature of the other.
The X-axis represents the in-phase carrier and the Y-axis represents quadrature carrier.
