Signalbearbetande enhet med intern klocksignal

摘要

A signal processing arrangement processes an incoming bit position carrying signal and produces an outgoing bit position carrying signal. The arrangement comprises a signal processing unit for processing the incoming bit position carrying signal to produce an outgoing bit position carrying signal. The incoming bit position carrying signal is time-controlled in relation to a first clock signal. The outgoing bit position carrying signal is time-controlled in relation to the first clock signal. A second clock signal having the same frequency as the first clock signal is used for processing the incoming bit position carrying signal into a processed incoming bit position carrying signal within the signal processing unit. A synchronizing unit synchronizes processing for the signal processing unit by changing the time-relationship of clock pulses of the second clock signal to synchronize with the incoming bit position carrying signal. Buffer circuits store the processed incoming bit position carrying signal. The timing of the processed incoming bit position carrying signal can be changed to synchronize with clock pulses of the first clock signal before the processed incoming bit position carrying signal is output as the outgoing bit position carrying signal.
