ABSTRACT:
The invention is directed to an improved scrambler capable of self-calibrating output signals. In one embodiment, the scrambler provides an encoded signal along separate signal pulses. A portion of one signal is made to correspond to a portion of another signal to thereby self-calibrate the signals. Also, portions of the incoming video signal are forced to correspond with internally generated voltage level signals.
