ABSTRACT:
A data communication system receives data signals transmitted via a signal path and applies to the received signal a high-pass function including a low-pass filter and a summing circuit. The signal is low-pass filtered, and the summing circuit subtracts the filtered signal from the received signal to generate a high-pass signal, which is summed with a quantized-feedback signal to generate a recovered data signal. The quantized-feedback signal is provided by applying to the recovered data signal a low-pass function having a transfer function which is substantially complementary to the transfer function of the high-pass function. The low-pass function low-pass filters the recovered data signal to generate the quantized-feedback signal.
