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.
