IQmodulaatio
IQ modulation is a technique used in digital communication systems to transmit information over a carrier wave. It is a form of amplitude modulation (AM) where the amplitude of the carrier wave is varied in proportion to the amplitude of the modulating signal. The modulating signal is typically a complex signal, consisting of two components: the in-phase (I) component and the quadrature (Q) component. These components are orthogonal to each other, meaning they are 90 degrees out of phase with respect to the carrier wave.
The process of IQ modulation involves combining the I and Q components to form a single complex
IQ modulation is widely used in modern communication systems, including wireless communication, broadcasting, and satellite communication.
