SIGNAL PROCESSING UNIT

摘要

A signal processing unit (1) in which incoming bit-position carrying signals (2') are time-controlled in relation to a first clock signal (3), and wherein outgoing bit-position carrying signals (4) are time-controlled exactly in relation to said first clock signal (3), and wherein signal processing procedures carried out internally in the unit (1) require the presence of the bit positions of the signal (2') and the clock pulses of a clock signal (3'). The signal processing carried out internally in the unit (1, 20) is controlled by the clock pulses of a second clock signal (3') which has the same frequency as the first clock signal (3). The synchronization required for the internal signal processing is achieved in a unit (13) by changing the time-relationship of the clock pulses of the second clock signal (3') to synchronism with the bit positions of the signals (2'); in that the thus processed data signals (4') can be stored in buffer circuits (10), wherein a time-controlled relationship belonging to the process signals (4') can be changed to synchronism with the clock pulses (3a, 3b) of the first clock signals (3) before they appear as outgoing signals (4).
