Abstract
To transmit fidelity the information, at long distances, was from the beginning, a great human dream. The information signal, when transmitted from the emitter to the receiver, suffers attenuation and distortion. Then, it is necessary to use frequently a regenerator to restore the original amplitude and also to retime the bit original period. The amplitude can be restored with an amplifier with AGC (Automatic Gain Control) and the bit duration can be retimed with a synchronizer with AFC (Automatic Frequency Control).
