Resumo(s)
This work studies the prefilter bandwidth effects in four asynchronous sequential symbol
synchronizers. We choose three different bandwidths, namely B1=∞, B2=2.tx and
B3=1.tx, where tx is the bit rate. First, we developed various synchronous prototypes.
After, we developed various asynchronous prototypes. The synchronizer has two variants,
which are the reference standard operating by both transitions at bit rate and the new
proposal operating by positive transitions at quarter bit rate. Each variant has two
versions, namely the manual and the automatic. The objective is to study the prefilter with
the four synchronizers and to evaluate their output jitter UIRMS (Unit Interval Root Mean
Square) versus input SNR (Signal Noise Ratio).
