Prefilter bandwidth effects in asynchronous sequential symbol synchronizers based on pulse comparison operating by positive transitions at half bit rate
This work investigates the prefilter bandwidth effects in four asynchronous sequential bit synchronizers. The prefilter bandwidth is changed between three discrete values, namely B1=∞, B2=2.tx and B3=1.tx, where tx is the bit rate. The synchronizers distinguish 2 variants, one asynchronous by both transitions at rate and other asynchronous by positive transitions at half rate. Each variant has two versions which are the manual and the automatic. The objective is to study the three prefilter bandwidths with the four synchronizers and to evaluate their output jitter UIRMS (Unit Interval Root Mean Square) as function of the input SNR (Signal Noise Ratio).
