Decision level setting method for analog to digital conversion of multi-level analog signal in digital receiver, involves using difference of low and high level signal, and high level signal as initial values and sampling signal

摘要

The high level signal (UHIGH) and difference (dU) of high and low level signals are set as initial value. The input signal is sampled and decision level is determined based on the sampling result, such that the decision level lies between the high and low states. An independent claim is also included for digital receiver.
