发明名称 Data transmitter baseline wander correction circuit
摘要 In a terminal coupled to a computer network, a circuit for compensating for the baseline wander of received digital signals. The terminal is AC coupled to the computer network by a coupling transformer. The received digital signal is summed with a correction signal. The resulting summed signal is input to a comparator. This comparator compares the summed signal to a predetermined baseline level. Thus, the output signal from the comparator is fixed at the baseline level. The correction signal is the difference between the summed signal and the output signal from the comparator. The correction signal is filtered and amplified before being fed back to the comparator.
