Question

Advantages of in phase and quadrature phase components

Answer 1

This shows the points in the complex plane where, in this context, the real and imaginary axes are termed the in-phase and quadrature axes respectively due to their 90° separation.

Answer 2

In electrical engineering, a sinusoid with angle modulation can be decomposed into, or synthesized from, two amplitude-modulatedsinusoids that are offset in phase by one-quarter cycle (π/2 radians).
