Abstract:
1. A full duplex transceiver for transmitting and receiving communication signals, the transceiver comprising: 1 to N sample and hold circuits, each sample and hold circuit receiving a first signal comprising a far-end signal, and receiving a replica signal including an echo signal and a cross-talk signal, wherein each of the N sample and hold circuits receives one of N clock signals, and wherein a phase of each of the N clock signals relative to the other (N−1) clock signals is dependent on the value of N; and a plurality of subtraction circuits, each subtraction circuit receiving an output of at least one of the sample and hold circuits, each subtraction circuit subtracting at least a fraction of a sampled and hold replica signal from at least a fraction of the output of the at least one of the sample and hold circuits.
