![Conceptual transmitter structure for QPSK. The binary data stream is split into the in-phase and quadrature-phase components. These are then separately modulated onto two orthogonal basis functions. In this implementation, two sinusoids are used. Afterwards, the two signals are superimposed, and the resulting signal is the QPSK signal. Note the use of polar [[non-return-to-zero]] encoding. These encoders can be placed before for binary data source, but have been placed after to illustrate the conceptual difference between digital and analog signals involved with digital modulation.](https://commons.wikimedia.org/wiki/Special:FilePath/Transmisor QPSK 2.png?width=200 "Conceptual transmitter structure for QPSK.
