From the diagram, it can be seen that the envelope of the signal follows the contours of the modulating signal.One of the aspects associated with amplitude modulation is the sidebands that are generated. These govern the bandwidth of the signal and as such they are of great importance.It...
The basic type of pulse modulation is known as PAM or Pulse amplitude modulation, where the signal can be sampled at regular intervals & every sample can be made relative to the modulating signal’s amplitude on the sampling moment. The above block diagram of PAM shows the PAM signal generati...
The constellation diagram examples shown are based on 64 QAM modulation and use the following basic settings: maximum possible DVB data transmission rate of 6.92 Msps or 41.73 Mbit/s (64 QAM); Cosine roll-off filtering with roll-off factor r = 0.15 and PRBS (pseudo random binary sequence) ...
