Measurements on the timing recovery performance of partial-response class-4 signalling

The timing recovery performance of partial-response class-4 signalling is experimentally determined as a function of transmit filter bandwidth, transmit filter rolloff and tuned circuit misalignment in the timing recovery circuit of a baseband transmission system operating at the ISDN basic access rate. The implications for echo cancellation are briefly discussed and some general properties of partial-response class 4 signalling are presented.
