Quadrature phase-shift keying (QPSK) modulator varies the signal's phase to transmit information.
Quadrature phase-shift keying (QPSK) transmission
Explore hands-on how a QPSK signal is generated and demodulated. Click on any wiring to open a scope and see how the QPSK signal is generated and demodulated. Check the transmission spectrum for different pulse shapers. Vary further parameters like carrier frequency etc.
All symbol transitions are possible.
