Digital modulation basics, part 2: QAM and EVM

In Digital modulation basics, part 1 we examined the concept of quadrature modulation and signal generation. We showed a common block diagram for generating a quadrature signal (Figure 1). There is a corresponding receiver block diagram to extract the Inphase (I) and Quadrature (Q) components of the signal (Figure 2). The signal is converted to… The post Digital modulation basics, part 2: QAM and EVM appeared first on Electrical Engineering News and Products.
