Digital receiver with adaptive threshold valves

摘要

A digital signal processing circuit (10) stores the peak value of the input signal on a storage element (26). The stored peak value is converted to a digital value (33). A ratio circuit forms a percentage value (36) that is a percent of the digital value (33). The percentage value (36) digitally stored and is used to form the threshold voltage (39). The threshold voltage (39) is compared to the input signal to produce an output (23). <IMAGE>
