How to optimise digital modulation accuracy in an IQ modulator? Bruce Hemp and Peter Stroet from Linear Technology describe how a vector signal analyser helps ...
Direct modulation of a laser 1 has always been used in optical telecommunications. Although distance–capacity product capabilities using this approach have been limited, it represents a very ...
Half the bits are represented on the real axis and half the bits are represented on the imaginary axis. The in-phase and quadrature signals are independent level Pulse Amplitude Modulation (PAM) ...
