ABSTRACT:
An analog signal is converted to a digital signal by two analog-to-digital converters. The first converter digitizes the analog signal to produce a first series of samples of the signal. The second converter digitizes the analog signal after it has been shifted in phase by 180 degrees to produce a second series of samples. A digital adder then subtracts the second series of samples from the first series to produce the digital signal.
