Quadrature amplitude modulation (QAM) is a modulation scheme in which two sinusoidal carriers,
one exactly 90 degrees out of phase with respect to the other, are used to transmit data over
a given physical channel. One signal is called the I signal, and the other is called the Q signal.
Because the orthogonal carriers occupy the same frequency band and differ by a 90 degree phase
shift, each can be modulated independently, transmitted over the same frequency band, and
separated by demodulation at the receiver. For a given available bandwidth, QAM enables data
transmission at twice the rate of standard pulse amplitude modulation (PAM) without any degradation
in the bit error ratio (BER).

DC-motors-SimPwerSystems
It is about the modeling and the simulation of the D.C machines under the Matlab software into which the libraries Simulink and SimPowerSystems are integrated. These libraries contain blocks of modeling which allow indicates it, simulation, the implementation and the system monitoring of communication and processing of the signal. The objective thus is to study the operation of the various types of D.C machines.
