Charge-coupled-device all-analog wave-form scrambling |
摘要 |
A scrambled analog signalling system having a source of analog signals to be sent to a receiving device is comprised of a multiple stage charge coupled device (66) having analog signal input terminals connected to receive analog signal samples from said source of analog signals. The multiple stage charge coupled device having N stages, corresponding stage taps, and an input clock signal. A shuffling circuit (68) having a first input connected to the N stage taps for receiving the analog signal samples and second input for receiving a random seed (67) signal to cause a random reordering of incoming analog signal samples, a source of random seed signals connected to the second input, and an output device (72) connected to receive a stream of the analog signal samples which have been shuffled according to a mapping code carried by the random seed signal. A filter for reconstructing the analog signal in its scrambled format, and a transmission system for conveying the analog signal in its scrambled format to the receiving device. |
