A feedforward tracking filter (FTF)adopting 2 bandpass filters (BPF) and feedforward control to provide fast and reliable acquisition,phase and frequency tracking ability is proposed.Various BPF configurations are used in the analysis of the FTF transient behaviour.The results show that for the same noise bandwidth,the FTF using two double-tuned BPF's provides the best performance and the acquisition is not degraded by the inter-burstinterference (IBI).Input-output signal-tonoise ratios are given.Experimental results are also presented.
